I totally loved the authors' book The Wife Between Us, so I was thrilled to get an ARC from Netgalley.

Jess sneaks into a psychological study and is befriended by the doctor giving the study, Dr. Lydia Shields. Dr. Shields makes Jess feel special and then "extends" the study for Jess' cooperation in other tasks for which she is paid handsomely. Jess has problems so this seems like a dream come true at just the right time. However, what cost will Jess have to pay the more she trusts Dr. Shields? And, who IS Dr. Shields, really?

I wanted to read this automatically without even reading the description on Goodreads because I so enjoyed the authors' first book, I figured this would be just as good. However, I thought it lagged in some places and quite a few times, I found myself thinking, "Who would actually THINK like this?" I just found a lot of parts to be unbelievable and while The Wife Between Us, delivered a twist to me at least, I felt this one did not. Nothing really surprised me, even though I see people on Goodreads praising the twists and turns. I am actually giving it 2.5 stars because it did keep me interested enough to finish it pretty quickly, however, while this may not have been what I was hoping for, I would still recommend it because I think people will really enjoy it upon it's early 2019 release.

WOW. this book was so full of twists and turns that I was on the edge of my seat from start to finish! I really liked this one and appreciate how well written it was. There are so many books out there that it is hard to be different from the rest and I think Greer Hendricks and Sarah Pekkanen definitely achieved that with this book!

WOW! Just when I thought 'The Wife Between Us' was going to be hard to top, 'An Anonymous Girl' ends up being even better! It's best to go in blind so I am not going to mention any of the plot. There are a ton of thriller books that are 'over-hyped' but this one will deserve ALL the hype I know it is going to get. Greer Hendricks and Sarak Pekkanen are a writing duo forced to be reckoned with. The writing is flawless and I ended up reading this until 3:00am because I had to know how it was going to end! Everyone is going to ask, if there is that one major twist like there was in The Wife Between Us. There isn't just one major twist. There are several twists that will give you whiplash and you will be thinking 'what just happened!' There were many moments when I thought I knew where the story was going, but I ended up being wrong! Pre-order this bad boy and know you are in for a real treat!
One of my favorites!

Thank you to St. Martin's Press for sending me an early reader's copy in exchange for an honest review!

I really enjoyed The Wife Between Us, but I read it around the same time as The Last Mrs. Parrish so it ended up feeling a bit repetitive at the time. This is definitely not the case with The Anonymous Girl because I feel as though the authors really came into their own in this second novel. The concept is fascinating, the writing is sharp and I ended up reading most of the book in one sitting because the alternating perspectives kept me wondering about the twists and turns that awaited me. I'm sure that this book will get a lot of buzz in the coming months and it deserves all of it.

Thank you to NetGalley and St Martin's Press for an advanced read in exchange for this review.

Jessica signs up for a psychological study about on ethics and morality. She thinks it's just a few questions to answer for Dr. Shields, and then she will get paid. Soon she finds herself doing outings for $$$$. Dr. Shields is manipulative, and Jessica wonders what exactly she signed up for.

Okay, this is a really cool premise! However, a lot of it is kind of far fetched. If you read it and don't think about how out there it sounds, it will be an enjoyable and pretty cool read. I did that at first. Afterwards I realized that this likely would not pass in the real world. Jessica is likeable, and you'll hope that nothing bad happens to her. There's a lot of mystery around Dr. Shields which is fun to unravel. Pretty enjoyable read overall! 3/12, but I'll round up.

Could you tell a lie without feeling guilt?

I actually squealed out loud when I received an advanced copy of this book. For real, I squealed. I loved The Wife Between Us, so I couldn’t wait to crack this one open. It quickly jumped up my TBR shelf to the number one position.. But then I got nervous. What if it isn’t as good as The Wife Between Us? What if I have it so hyped up to live up to that?

I’ll be honest, I went into An Anonymous Girl not even knowing what it was about. It wasn’t until I had read the first 10% of the book that I went and read the blurb on Goodreads.

Seeking women ages 18–32 to participate in a study on ethics and morality. Generous compensation. Anonymity guaranteed.

I’ll say it: This book is very different from The Wife Between Us, if you’re coming into the book expecting those big twists, you might be disappointed. An Anonymous Girl was just a mindbender from the beginning. I constantly questioned everyone’s motives. I was suspicious of everyone and everything. I never knew what was really going on. The second I thought I had it figured out I was proved wrong.

I haven’t read a book that had me this engrossed in a very long time, I was up all night “just one more chapter, just one more!” Seriously, it’s that good. Everyone should have this book on their radar, pre-order, mark the release date in your calendar, whatever you need to do, it is that good!

Thank you to NetGalley and St. Martin’s Books for providing me this book in exchange for an honest review.

You know that feeling when you discover a new author(or in this case two) and you loved their first book(The Wife Between Us) and you get approved for an e ARC for their second book, An Anonymous Girl? You don't, well let me say for me it is like winning the book lottery and then figuring out how many hours of work and life will stand between me and the book(46 hours exactly between approval and settling in at the beach with this one). Did this book disappoint? It absolutely did not. There were so many twists and turns that kept me guessing until the end and I changed my mind often trying to figure out where this was headed.
Jessica Farris works hard to afford her tiny apartment and life in NYC. When she learns of an opportunity to participate in a research study, she thinks she will make some much needed easy money. However, Dr. Lydia Shields seems to have her own agenda and Jessica is about to play a very important role in her research. Dr. Shields wants much more than a completed questionnaire and as the things she asks Jessica to do become more complicated, the suspense builds. I can't say much more about the plot without entering spoiler territory, but I will say I was furiously flipping pages so I could figure out what was really happening.
A very good follow up to The Wife Between Us and I recommend The Anonymous Girl to mystery and thriller lovers. The book description had all I needed to know to grab my interest and kudos to these two very talented authors.
I received an e ARC from St. Martin's Press through NetGalley.

Oh boy, oh boy..... An Anonymous Girl is a collaboration between Hendricks and Pekkanen. Their other book The Wife Between Us, to me was one that could not be outdone by another book. Boy was I wrong. This story is about a young woman, Jess, who signs up to get paid to perform a study. Jess has no idea what is in store for her and she is becoming more and more paranoid by the therapist giving the study. I really under estimated this one. I felt that the writers did a wonderful job of emphasizing certain characters that enhance the story. The main protagonist is Very likeable. This story is gripping and has control of you the minute you start reading it. I wanted to get to the end so fast just to see what was going to happen. Not the jaw dropping ending that has appeared in their other collaborations but a very good twist none the less.

Thank you to netgalley as well as the author/publisher for giving me the opportunity to read this book in exchange for my honest review.

5+++ ⭐️ out of 5

THANK YOU for this ARC!

After reading The Wife Between Us, my expectations for every Hendricks/Pekkanen book are sky high! An Anonymous Girl did not disappoint!

Hendricks and Pekkanen are quite possibly the queens of psychological thrillers. This is an edge of your seat, what will happen next, type of thriller. A novel written in the POV of a disturbed and obsessive "medical professional" and of a seemingly typical young woman with a secret and a few destructive behaviors, this book will hook you from the first page. You will not want to stop reading this book. I couldn't wait to see how the story unfolded but was sad to see it come to a close. Amazingly thought out characters with just enough unreliability to intrigue you.

I am ready for the next Hendricks/Pekkanen book!

This was by far one of the best books I've read in a long time! It sucks you in from page 1, where an established therapist is performing a study. It happens by fate that a girl in desperate need to make ends meet catches wind of said study and it slowly spirals downhill from there.

This is the 2nd book read by these authors and it is another one of those endings that will shock you! Very well written and fast paced.

Thank you to the publishers for letting me read this fabulous ARC in exchange for an honest review.

I voluntarily read and reviewed an advance copy of this book courtesy of NetGalley. All thoughts and opinions are my own.

As with their first book, the characters are all well developed, believable and engaging. There are a lot of twists and turns in this creative and unique story.

I highly recommend this psychological thriller. I predict this book to be a big hit you won't want to miss reading. If you liked Gone Girl, Lies She Told or the Other Girl, you will enjoy this book. It has a fun "boil the rabbit" feel to it you won't want to miss. I will eagerly await the next book written by this dynamic duo, Greer Hendricks, Sarah Pekkanen.

Excellent story! This author is one to watch out for! Very fresh material and keeps you on the edge of your seat the entire time! Looking forward to reading more by this author!

I tore through "An Anonymous Girl" in one day. While it didn't have a jaw-dropping twist like their last collaboration, "The Wife Between Us," I actually liked this book better. The characters, particularly the male characters, were better drawn than in their previous novel. The protagonists had very distinct voices and I enjoyed being in each of their heads. I'm a little conflicted about the ending, partially because it seemed a bit too abrupt and easy but I did appreciate the novel's central question of morality arising one last time. I would recommend this book and appreciate being able to read it prior to publication.

Wow where to begin! I loved this book so much! I enjoyed the main character Jess and I struggled with every step she took like I was right next to her. This definitely was a psychological thriller! The story starts with jess a woman who is a struggling make up artist In New York. She decides to participate in computer questionnaire at a university for extra money. The questionnaire consists of personal questions. After she completes she’s contacted by dr Lydia who was in charge of the the assignment and Jess is told she was chosen out of every participant to continue and she will be paid. Once she gets to know dr Lydia and the assignments Jess starts to realize there may be more to dr Lydia than the perfect woman she portrays and she may be being used by her. The assignments dr Lydia puts Jess in are picking up a man at a bar and seeing if he calls her , calling random people from a phone log. Jess starts to worry maybe she shared to much of her life and secrets with dr Lydia and what is dr Lydia’s true motive. I loved how the story goes from Jess and dr Lydia’s point of view and this defiantly had me eagerly turning each page!! I want to thank the publisher for an advanced copy for my review!!!

Given the massive hit that was the first novel these two co-authored, The Wife Between Us, there must have been so much pressure when penning their follow up. However, I am happy to report that The Anonymous Girl more than surpassed my expectations and totally blew me away. Another game of cat & mouse - but who is playing? What starts out as a study on morality and ethics quickly escalates - and will have the reader and the characters asking questions!

Don't miss this one in January - it's bound to be a huge hit!

The give and take among the characters in this novel is just very realistic and gripping from nearly the first page. Most of the descriptions and situations are very realistic, and many of us can empathize from the major plot points. While some of the third-person descriptions is a bit forced, overall I really was taken with the story and couldn't put this book down. If you are looking for a somewhat different take on a psychological thriller, this should be the book you read next.

Thanks does not seem to be enough for this precious ARC from Netgalley & St. Martin's Press. I was honestly floored when my wish was granted and I received this well before publication. The Wife Between Us set the bar high - as soon as I found out about this sophomore thriller from Greer Hendricks & Sarah Pekkanen, I was perched impatiently on the edge of my seat. It had been years (Since Gone Girl) that I had to stop and put down a book and slow down to digest the mammoth of a plot twist that was The Wife Between Us. I remember thinking two things after I finished: It's going to be hard as hell to top this, and I can't wait for their next book. I don't remember it specifically, but my sister recited a quote to me a while ago, and it went something like, "You are a different person to everyone who meets you." It was profound and disconcerting, in a way. In this book, the therapist in this thriller describes how five seconds can change a life. My life is changed by quotes. Quotes that make me stop, contemplate, and reevaluate. The quote my sister told me was one of those moments. Every single person we meet has a different view of who WE are as a person, a friend, a colleague. This book didn't have a specific quote, but the descriptions from the therapist about little observations and tells that each individual has, has left me baffled. I wonder what it must be like to be so analytical, down to establishing small stepping stones to learn someone's habits, to be able to tell a story of their true thoughts and honest feelings by simply watching and cataloging their body language. It is incredibly impressive. I imagine this is how people in power think: seven steps ahead, anticipating the tells of their subjects. It is spooky. Add that ability with the sterility and talent for logical thinking and you have a true mastermind evil genius. There is something absolutely horrifying and unsettling about perfection, isn't there? So while there was no twist that made me drop my book and my jaw, the characters were enough to make you stop with chills. The characters and descriptions were Stephen King-like that way. Sometimes, in this day and age, we over look the truly simplistic sinister character in favor - for lack of a better word - of the all out crazed, sloppy maniacs. It doesn't have to be bloody, gory, topsy-turvey to be scary, to send a chill down your spine, to stand your hair on end. The scariest thing is someone knowing and anticipating our every move and using them against us for our own demise. What is more evil than that? Someone trustworthy betraying you with their calculations. Someone who is supposed to have your best interest at heart. It truly brings like to the selfish nature of humanity: it doesn't matter who is destroyed in our path as long as our questions are answered, as long as our own needs are met. An Anonymous Girl occupied my thoughts when I was not reading, captured me, pulled me in and took me on a subdued, thrilling journey. This was not comparable to The Wife Between Us - so if you are going into this like I initially did, look for something other than a twist. Look for how well crafted this is. How seamless the two writers come together. This was absolutely fantastic and I will forever be a loyal reader.

First off, thank you for letting me review this book. This book just didn’t do it for me. I just kept things while I was reading it was really?? Who would actually do this stuff!? I didn’t like the flow of the writing and the wording used and it just was a drag for me. A few good twists and turns but that’s aboit it.

Omg Wow. Thank you so much ST. Martin's Press and Netgalley for giving me the honor and opportunity of reading this ARC. I actually have not yet read The Wife Between Us, so I did not go into this with any expectations that were based on that book.

This story draws you in from page one and keeps you hooked until the very end. I loved the two main characters, Jessica and Dr. Shields. I loved the back and forth between their characters. I enjoyed the mild confusion I felt throughout the book, and the curiousity it gave me to keep going. I loved how this book was a thriller but did not rely on gore to shock the reader, therefore appeally to all ages and fans of suspense. This book is extremely well written, descriptive while not going overboard. Loved the setting of New York City during the holidays. There were so many things I loved about this book I'm sad it's over. Very original and refreshing. So many thrillers I feel like I'm reading the same thing, never once did I feel that way with this book.

Preorder this now, but warning do not start this unless you can keep reading, you will not want to put this down. It's so good, I read it was already sold and will be made into a series. Which I can't wait for.

This was an amazing physiological thriller, and I can not wait to check out The Wife Between Us.

When the offer for this book arrived in my email box from the publisher, I almost passed on the book. I had tried the previous book by the authors earlier this year and disliked it so intensely, I couldn't even finish the book. I actually added to a list of "always avoid these authors". But. I decided to give this a shot anyway, and the description and cover did appeal to me.
Wow. I am so glad I gave this a shot! I haven't read many can't-put-it-down books in recent years, and so many of the psychological thrillers on the best seller lists are so predictable, I avoid them. This one was different. The twists happened chapter by chapter, rather than a big reveal. And, for the first time in months, I didn't see the ending coming. I accomplished nothing I'd planned to do, did only very minimal chores, and lost a few hours of needed sleep because I HAD TO finish this book. I HAD TO know what happened next. When I came to the last page, I was actually breathless.
The only criticism I have is the wording for the chapters narrated by Dr Shields. The wording is just so awkward. It didn't flow, and it didn't fit the character of Dr Shields that I was building in my mind. And I felt like it was inconsistent. I read some passages to my husband, and he agreed that the phrasing was a turn off, enough to actually say "Why are you still reading this?" Well, obviously because I was caught up in the story! :) And the chapters narrated by Jess are much different, very readable and the flow is fine.
