his is a brilliant story and a perfect slow burn romance. Ro Devereux has created an app called MASH which can predict the future. It can tell you what job you’ll have, where you will live, how many kids you’ll have and who your perfect romantic match is. But after telling her cousin about the app which she created for her senior project at school, it’s soon download more and more times and quickly goes viral attracting the attention of some powerful influencers.

I loved this story from the start. The story begins with Ro, short for Rose, as she’s heading towards the hall in her high school to make a presentation for her senior project, months before it’s actually due. On the way to the presentation she encounters her nemesis Miller, a boy she used to be friends with but who now ignores her. Miller gets under Ro’s skin, but she doesn’t let it stop her presentation and soon after presenting to her teachers, the app goes viral when her cousin shares it with people she knows. The app, MASH was never supposed to get out into the real world, it was only supposed to be part of Ro’s senior year project to show her dad that she is capable of creating something so she doesn’t have to head for university and get into debt which her family can’t afford, but after the app goes viral and is all over social media, Ro is invited by a company who want to invest in her app and make it more accessible to everyone.

I love what happens in this story as Ro eventually signs up with the tech firm and the app becomes bigger and bigger as more people download it and even the press gets interested in it. But in order to attract the really important investment of one particular company, the people now working on MASH want Ro to get together with her own MASH match. Ro soon discovers that her match is Miller though, the boy she doesn’t talk to and who hates her as much as she does him. The story is good as Ro and Miller soon find themselves agreeing to pretend to be the perfect couple for the sake of selling the app. I don’t want to reveal too much, but the story does move on with us finding out more about Ro and Miller’s past and how the pair used to know each other well and how they ended up so hateful of each other too. The story is told from Ro’s perspective, in the first person, throughout and I like what happens as she and Miller end up spending a lot of time together and we slowly unravel the secrets of their shared past and why their relationship towards each other is so cold today. I also love how we find out more about Ro’s other relationships with her best friend, dad, neighbour and especially how her mother’s disappearance from Ro’s early life has affected her growing up.

A lot happens in the story with MASH becoming very popular and I like how this story isn’t just about Ro, but gives us an insight into the deeper questions of human behaviour too and its unpredictability. As the story ends up building up to its conclusion some dramatic things happen to both Ro and Miller and I love how this story kept me guessing as to what would happen although there is this perfect slow-burn romance brewing too. There were some dramatic moments in the story, some sad moments too, and throughout it I love how Ro’s relationships with characters changes and how she grows as a character too. The ending is brilliant, I like what Ro discovers about herself and how she feels about MASH towards the end. The ending feels like a good and perfect ending, with all of the characters growing in the end and some interesting revelations and twists that I wasn’t expecting too.

The story does have the occasional use of the f and s swear words, and does feature some heart-breaking moments like a death, but nothing else too upsetting. I do like how Ro really grows in this story and how all of the other characters end up resolving some difficult issues too. Overall I have really enjoyed reading this. I love a good slow-burn romance and the idea of the app that can predict your life was so interesting too. The title makes sense once you read the book, and I just love how satisfying this story felt after I finished it. It’s definitely a book I will want to read in future!

To have had the love Ro and Miller have when I was eighteen! Seeing the main character Ro, an eighteen-year old, forge her own path, have the strength to do the right thing no matter the consequences, and evolve was a delight to read. Even though Ro is going through a rather difficult time, dealing with several major things at once, that's when she is able to trust and form even deeper relationships with her loved ones. That's when she shows her true self - courageous and with a big heart. There's beauty that comes out of the chaos. What I loved most about the book is the reminder that it is ultimately up to ourselves what our future holds. Yes, an algorithm can predict, but we are the ones who get to decide who we are in our future. How thrilling and inspiring.

Thank you to NetGalley and HarperCollins Publishers for the eARC!

i cannot believe this is a debut novel.
the writing is fantastic, and really screams YA without screaming YA, if you know what i mean. the prose is clearly up to date on how teenagers actually talk and react to things, and doesn’t feel like an adult was attempting to speak through teens (which yes, is apparently an easy mistake for authors to make).
i really enjoyed the story: yes, it’s a romcom, but it’s also more than that. it’s a coming of age book, in which ro overcomes personal struggles and learns important lessons in a very relatable way for any high school senior. also, shoutout to the seamlessly incorporated flashbacks - i felt like we got the right amounts at the right times and in a natural way within the narrative, which is so much not a given.
this not to say, however, that the romance arc wasn’t on point, because it absolutely way. this book has two of my favorite tropes: slow burn and childhood best friends to ‘indifferent enemies’ to lovers, which are executed FLAWLESSLY. you can feel what the characters are feeling at each separate stage: during the flashbacks ro and miller are clearly inseparable (and miller so in love with ro), in the fake dating stage the tension is so strong you could cut it with a knife, and when they finally make up they’re so, so sweet.
i’m not very articulate, but i loved this book. so much. it’s one of those i actually would read more spin-offs about, maybe exploring some of the other characters’ stories too.

This was very interesting, loved the characters! Had a fun time learning about them and seeing their progression through the story. Excited for this to come out!

4.75/5 stars! Eep! This is like the YA version of "The Soulmate Equation." I love dating apps/prediction-based stories and this is a great addition to this genre. There is also the friends-enemies-slow burn lovers angle between Ro and Miller that had me swooning throughout this whole story. Although Ro isn't a perfect character, she is achingly genuine, flaws and all. I'm also a fan of the fake dating trope so I felt like this book was written just for me.

I received an advance review copy for free through NetGalley, and I am leaving this review voluntarily

This book gave me so many feels, and I'm excited to read more for Ellen! Ro is an ambitious character, who learns a lot about herself in this book. I found myself instantly invested in her journey and choices, and the overall idea of MASH. Would I want to know my future in that way? Who would I react if I did.

I plan on posting a full review on my blog in a few days.

Seven Percent of Ro Devereux is the debut novel for Author Ellen O’Clover. I am thankful to both NetGalley and HarperCollins Publishers for the eARC in exchange for my honest review.

Being a child of the 80’s and 90’s, I was beyond excited when I read the synopsis of this book and saw that it was about a teenager who created an APP based on one of my favorite childhood games, MASH. If you know, you know!

Ro Devereux’s mother left when she was very young, and she grew up with Miller, her very best friend in the whole world, until they had a huge fight their freshman year and haven’t spoken since. Now, they are seniors in high school and she is trying to figure out all the answers to life.

For her senior project, she decides to work with her neighbor/mother figure, a retired behavioral scientist, to develop an APP based on a series of highly scientific questions that will help predict her future.

Where will she live? What kind of career will she have? How many kids will she have? And most importantly, who will be her match?

The APP blows up on social media and suddenly Ro is on a whirlwind journey working with a tech company that may not have her APP or her best interest at heart.

Definitely pick up this debut novel and find out what happens!

4 incredibly bright stars 🌟🌟🌟🌟

I can’t wait to see what Ellen O’Clover writes next!

Rose "Ro" Devereux is a high school senior who designs a future predicting app called MASH for her senior project. But when her project goes viral, she finds more success and interest than she would have expected. Things continue to blow up when the app's "match" function pairs her with her former best friend Alistair Miller, who she has no longer speaks to.

There's so much to love about this book. Ro's relationships are at the center of the story. I loved Ro's relationships with her father, best friends, and mentor Vera. But this book also explores themes finding your path/yourself, the complexity of humans, parental abandonment, repairing relationships, and the family we choose for ourselves. This book was fun, and the themes felt really important for young readers.

I think YA readers will love this one! Thanks to HarpersCollins and NetGalley for an eARC copy.

this book was so interesting to me because its whole plot revolves around the nostalgic game MASH which i remember playing often as a kid!

i love ro, ugh she’s so cool. i wish i was as cool as her but i also feel like i sorta connect with her. i use to be write/code for an animation story app and was massively into the coding side of things. i’m definitely not smart enough for STEM tho lmao.

okay but also can we talk about MILLER !! i deffs swoon over the bad boy characters but i was so obsessed with his nerdy self like i want 1000 millers thank you.

i honestly squeal over ro and miller!!

also how cool is the name ro devereux?!

the book does start off slow for the first few chapters but once it gets into the story i literally couldn’t put it down!

i really liked that even though this was a cute YA book it also dives into serious topics such as grief.

and i loved the ending!! it was so perfectly bittersweet💚✨

if you’re looking for a best friends to enemies to fake dating to friends??? to lovers YA romance - this is the one for you!

I enjoyed this fun, coming of age novel! Ro creates an app based off of childhood game MASH for her senior project. She has goals of working in tech right after high school but doesn’t expect for her app to take off right before the start of her senior year.

This book has a little bit of everything, growing up and figuring out the next step, friendship, romance, family expectations and loss.

Thanks to NetGalley and Harper Collins for an e-arc in exchange for an honest review of this book.

As someone who valiantly played MASH throughout my girlhood, SEVEN PERCENT OF RO DEVEREUX was an irresistible read for me -- a nod to the nostalgic with a compelling contemporary hook.

When the app that high school senior Ro builds as her senior project gains massive traction, she must team up with her estranged, former-bff Miller to fake date and model the app's future-predicting capabilities. But what happens when knowing your future creates doubt in the present? And how can Ro make peace with Miller and her own future?

This contemporary YA is fun and relevant, and O'Clover's writing style is engaging to the very end. It's also incredibly thought-provoking and touches on some really meaningful themes. It's got swoon, it's got humor and heart, and it's chock-full of the timeless elements of a rock-solid -- and enjoyable -- YA. Loved this debut.

And lastly, as a side note, I would just like to say: MILLERRRR! <3 I LOVE YOU. Consider me a Miller (and subsequently, an Ellen O'Clover) stan for life.

Thank you to Netgalley and HC for granting me access to this ARC. All opinions are my own.

I will post my review of this book when the Harper Collins Union strike is over because their needs were met.

A sweet friends to enemies to lovers story with unexpected depth and prose perfect for fans of Emma Lord.

The premise is entertaining- girl designs app that can predict the ideal future for anyone, only to end up matched with her estranged childhood best friend. But what drew me in was the author’s use of language, with beautiful quotes that jumped out to me and a heart wrenching dynamic between the two friends at the center of the story.

Plus it’s got fake dating.

The conclusion fell a little flat for me but the app premise was not what made this story compelling for me anyway, so I didn’t really mind.

I’m excited to read more by this author!

Thank you to HarperCollins Teen for sending me this ARC in exchange for an honest review.

Rating: 4/5
Release Date: Jan 16, 2023

I really enjoyed this book, it was a wonderful exploration of how much technology influences our life and how ultimately we can be the ones to either trust in the tech or not.

Pros:
-the characters were great, the romance between Miller and Ro was very cute and I liked the fake-dating trope (even though I normally don’t lol)
-the plot was really engaging and I enjoyed all of Ro’s moments of fame and confusion at the same time
Cons:
-none!
All in all a really fun read!

*Review to come on Instagram at a later date closer to publication*

I was lucky enough to receive an advanced copy of this book, and it's easily one of the best books I've read this year. I wish SEVEN PERCENT OF RO DEVEREUX had been around when I was a teen.

I loved Ro and instantly connected with her. The writing is tight yet lyrical, which made it so hard to put down. This book is refreshing in that it shows a modern take on teen problems while still embracing a sweet romance. The plot is smart, fun, and will hook your teen reader without a doubt.

Highly recommend.

I loved playing MASH as a kid, so when I saw that the game was the basis for app at the heart of Seven Percent of Ro Devereux, I knew I had to read this book.

Rose "Ro" Devereux loves coding, but when the app she develops for her senior project--an app based on the classic game MASH--catches the eye of a tech company, her world is turned upside down. Suddenly all her dreams are coming true, but when the app 'matches' her with Alistair Miller--former childhood friend and present-day enemy--Ro finds herself forced to face the past in order to discover her future. Combining a slow-burn romance and the influence of tech and social media, O'Clover's debut is a nostalgic yet modern YA romance that will have you cheering for Ro until the final page.

O'Clover has created an amazing cast of characters led by the FMC, Ro. Ro is incredibly smart and driven, but she's also fallible in completely believable ways. Her relationships with her father, with family friend Vera, and with best friend Maren are realistically written, and Ro truly feels like a high school senior without being overly dramatic. Bring in Miller, the MMC, who used to be Ro's best friend and who is a giant cinnamon roll, and you have an amazing enemies to lovers slow burn that is absolutely endearing. The supporting cast is well-developed, too, which makes the story even more enjoyable.

Ro's app brings a fun tech side to the story, and it was interesting to explore the pros and cons of being able to 'tell the future' using technology. In today's society, social media and apps have significant influence over so many aspects of peoples' lives, so being told what your future holds could very well have the potential to alter a person's path. The consequences of Ro's work end up being more drastic than she'd ever expected, and her responses to those consequences show her true character and change her own future in unexpected ways.

Seven Percent of Ro Devereux is an engaging contemporary slow-burn romance with an interesting look at the influence of technology and a fun cast of characters. O'Clover's debut will be a 2023 hit.

I love books that feature girls/women creating websites/apps, or doing anything in STEM. It's not the boys' league anymore. You also can't go wrong with either the enemies-to-lovers or friends-to-lovers tropes, which this book includes both of them. This is a very good YA read that I'll definitely be purchasing for my library, as I think we have a lot of young adults (maybe even some adults) who would enjoy this book!

Ellen O’Clover’s Seven Percent of Ro Devereux takes us on a journey of love, loss, heartbreak and reunion woven in exquisite prose. Set in gorgeous Colorado, Ro creates a senior project that predicts one's life path. Once it was sold and went viral the spiraling effects it had among users was jarring and painful. But throughout the story it had me rooting for the greatest gift of all….love! A must read!

Seven Percent of Ro Devereux was so fun and unique! Ro creates an app based on the classic game Mash and it blows up. The way the app takes the world by storm and the aftermath felt realistic and was thoughtfully handled.

I really liked Ro and Miller. They were both kind but flawed in a way that made them feel very human. I love a slow-burn romance and I enjoyed Ro and Miller's relationship, but I did feel like Ro very suddenly realized her feelings for Miller. I would have liked a bit more build up in her discovering her feelings.

I loved the side characters - Maren, Ro's dad, Felix, Autumn. I especially loved Vera and how she let Ro just be who she was and learn for herself.

I'm really looking forward to whatever Ellen O'Clover writes next.

SEVEN PERCENT OF RO DEVEREUX by Ellen O’Clover follows the title character, who created an app for her senior project. The app is called MASH and it predicts users’ future place of residence, occupation, and how many kids they’ll have with 93% accuracy. Never intending for it to go public, Ro is shocked when influencers latch onto her app, and it spreads like wildfire. Adding to the mayhem, a tech company reaches out for acquisition, but the caveat is they want to launch the partner matching segment of her app and for Ro to be the face of it. To her dad’s dismay, Ro agrees and matches with Miller, her childhood best friend and current archnemesis. If she can somehow get him to pretend he’s in love with her, the app's projected future is bright, and if not, everything Ro’s worked for could be in jeopardy.

From reading the blurb on this book, I knew two things: the likely structure of the book and that I’d probably like it. Having now finished the novel, I can safely say that while I was right on both accounts, the story took me by surprise! I wasn’t prepared for how deep and heavy this novel gets and found the commentary on life and the world as we know it to be the true meat of the story. It really made me think, and not in the pedantic sense. It did it through feeling— by bringing me along with Ro on her emotional journey. It’s profound in its reflection on assumptions, expectations, difficult conversations, and so much more.

That being said, the romantic element of the story is still a crucial piece of the narrative. Friends-to-lovers and enemies-to-lovers are the best tropes to exist, and this novel combines both of them. I like Miller’s character a lot (his goofiness, his love of Classics, even his tux!), and while at first, I had a hard time fully grasping why Miller and Ro didn’t talk to each other for three years, I did understand by the end. The nature of their relationship shows how life can sometimes get in the way of connection, but also, how sometimes it can be repaired with a five-minute explanation. I did want a little more payoff between Ro and Miller, but I respect that what happens between them is more of a subplot.

Overall, SEVEN PERCENT OF RO DEVEREUX is a great musing on what it means to go after your dreams and what sacrifices are worth it. It's a good reminder of the importance of staying true to your vision and intention, and more importantly, it leaves space for what it means to be a human, encouraging the open-ended exploration of that.

If you’re looking for a good cry, add this book to your wishlist.
