Chapter one felt old-school nobility, chapter two felt too modern and like a different book, and I ultimately lost interest in the story. As a woman in STEM, I was hoping this would be a slam dunk. I learned this book is a sequel, but this book focuses on Grey and Letty while book one focuses on Violet and Arthur based on the synopsis. I don't know that it's necessary to read the first to understand at least where the second is going. 3-4 stars for the target audience.

Thanks to NetGalley and Berkley for the ARC.

Six years ago, Miss Letitia Fenley made a mistake, and she’s lived with the consequences ever since. Readying herself to compete for the prestigious Rosewood Prize for Mathematics, she is suddenly asked to take on another responsibility—managing Athena’s Retreat, a secret haven for England’s women scientists. Having spent the last six years on her own, Letty doesn’t want the offers of friendship from other club members and certainly doesn’t need any help from the insufferably attractive Lord Greycliff.

Lord William Hughes, the Viscount Greycliff cannot afford to make any mistakes. His lifelong dream of becoming the director of a powerful clandestine agency is within his grasp. Tasked with helping Letty safeguard Athena’s Retreat, Grey is positive that he can control the antics of the various scientists as well as manage the tiny mathematician—despite their historic animosity and simmering tension.

As Grey and Letty are forced to work together, their mutual dislike turns to admiration and eventually to something...magnetic. When faced with the possibility that Athena’s Retreat will close forever, they must make a choice. Will Grey turn down a chance to change history, or can Letty get to the root of the problem and prove that love is the ultimate answer?

Letty and Grey are the standard. Let me repeat...Letty and Grey are the standard. If you cant tell I loved this book (and this is coming from someone who hates math lol) but I think this author accomplished creating characters who as individuals were so interesting and lovable on their own, but together were even better. There truly was not a moment where I was not rooting for them to be end game. I absolutely adored this book and would love if this author could write me my own fictional mad who reads books to me please and thank you.

It is always a delight to read anything by Elizabeth Everett. I absolutely love this series. Full of banter and wit. Feminist men & women and of course, swoon-worthy romances.

Elizabeth Everett has restored my love for historical romances.

A delightfully empowering historical romance perfect for fans of Evie Dunmore. It's surprisingly swoony!

This is different. The heroine was a little too modern but it was not too bad. She did not commit any serious actions that break the spell of a proper historical romance weave. It had great character development and arcs. The people had issues and misguided beliefs that actually healed and grew from. It lacked some of the manners and scenes that make historians so fun. but overall it was a good romance

I'm afraid this book was a case of reading it at the wrong time. I ended up DNFing it around 40%, simply because I couldn't get into it. However, I do still believe this book might be one I would enjoy. So hopefully I'll be able to give it another try in the future. For now, this is sadly 1 star.

Enjoyable victorian romance, enemies to lovers, women rights, loved Letty's family.

Thank you NetGalley for the ARC in exchange for an honest review.

Regency romance with a twist of mystery. Fantastic! Fans of Bridgerton will enjoy immensely. The characters in this book are excellent!

I was very excited to read this book! I really enjoyed the first book in The Secret Societies of London - A Lady's Formula for Love (bought the book based on my enjoyment!). I loved Arthur & Violet from the first book and I fell in love with Letitia and Grey in this book. I really enjoyed that there was equal time given to both characters throughout this book - it made me want to root for the couple even more! I also really loved their connections to other side characters in this book. This series has made any Elizabeth Everett book a must-buy for me! :)

Having your own dreams and aspirations is something all of us strive for, but we never have control on the road to get there. For Letitia her dream was in math, but she ends up working for an elite society directed to science. She is so focused on winning the Rosewood Prize for Mathematics that she just blinds herself from the community members especially, Lord Greycliff. Then Grey and Letty have to work together and foes turned friends turn into romance. This was an unexpected love story of two subjects that are not my forte. i am not going to lie, I was nervous reading this book and was hoping it wasn't filled with difficult science and mathematic vocabulary, but I was happy to see Elizabeth Everett focused on the relationship between Grey and Letty and the value of the Athena's Retreat which always draws my attention.

A satisfying romantic story combining the drama of the prestigious goals that await our paths, Elizabeth Everett remarkably crafted a joyful read. This book deserves 5 stars.

A fun historical romance with STEM representation. An easy read, and very enjoyable. There was other health representation as well which I always appreciate.

This was a fun, historical romance with the dash of science that I expect from this series. Letitia and Grey aren’t my favorite pairing - to be honest, I’ve been wanting a love story for Grantham since he was introduced - but I did enjoy their dynamic.
I liked that Grey was apologetic once he realized that the story he’d heard of Letitia’s past wasn’t accurate and that there was no disbelief on his part. I especially enjoyed that he was always supportive of the women’s work at Athena’s Retreat. I just can’t wait until it’s Grantham’s time to shine!

I loved this book. It is such a swoony, sexy romance. A broken hero and an unconventional and broken heroine, Grey and Letty are amazing. I just love their enemies to lovers story. And this love story is set against the backdrop of 1840s London and Athena's Retreat, a women's club for scientists and mathematicians. Letty helps to run the retreat and there is a lot of societal pushback against what the women are doing there. I love historical romances that pushback against the stereotypical norms of the time and you get to see women and men breaking free of societal bonds. And that is this book. I love it and it's beautiful and I can't wait to read the third book.

Bridgerton meets women in stem is my favorite new plot. This was a fun read and reminded me of the stem filled novels I've read (the love hypothesis and the kiss quotient. It's probably why i enjoyed reading this so much. So fun!

A Perfect Equation is an enemies to lovers’ story which I thought was delightful and I absolutely enjoyed. Letty Finley has been put in charge of Athena Retreat, a club for London’s women scientist, but doesn’t like the fact that she shares this responsibility with the one man she loathes. Nobleman William Hughes, Viscount Greycliff, caught Letty in a compromising position 6 years ago with his cousin and she’s been ostracized from good society. They both have a low opinion of one another but slowly learn that they have misjudged one another and see them in a new light. However, they both have different goals to achieve and unfortunately, they come in conflict with one another.

I love it when I come across something fresh and this story of a feminist mathematician trying to break the mold of what a woman’s role in Victorian England is brilliant. The fact that a group of women created their own social club in order to hide their experiments and work behind closed doors, makes for some interesting encounters when you just never know what might happen. For Letty, the author made math poetic and something to get lost in which made math look warm and comfy. The other characters in the story brought the whimsy and humor which definitely brought the story to life. A Perfect Equation is definitely a great addition to the Secret Scientists of London series, and I look forward to more. I would recommend reading the first in the series, A Lady’s Formula for Love, because you’ll really enjoy A Perfect Equation better to understand the setup for this storyline.

A Perfect Equation is a smart, funny and delightful story for any historical romance reader and shouldn’t be missed.

Letty is a STEM heroine for the ages. Loved this historic romance promoting slightly seditious women. The whole Rosewood thing made me crazy though. The romance between Letty and Grey was just right.

I love romance books that have "nerds" in them. This was a great addition to the ever-growing genre.

I picked this up not realizing it was a sequel, but I still really enjoyed it! I love historical romances with a feminist twist, and this was exactly that.
