This book was so amazing. I really felt like I was in the head and conciousness of Jessica and Dr. Shields. The book starts with such an interesting premise, Jess wants to be part of a study on honestly for money (and ironically has to lie about where the person who was invited to be the real partiipant was), that she really doesn't see the red flags that come up.

Dr. Shields has an interestng motivation for the study, a few times you think you might understand what she's after, but her real motivation is quite unusual and not what Jess or the reader would suspect. A few other characters come into play, but most of the action is between these two and one other I won't mention as s/he is best to be surprised by their identity, motivations and actions.

The characters are belivable and compelling. Readers will find themselves unable to put this book down to see how far Jess will go when Dr. Shields wants to continue using Jess for more and more involved experiments, and what her final motive is. The ending is unpredictable, yet totally believable for our characters.

This is a highly recommendded page turner.

Jessica Farris is a twenty-eight-year-old makeup artist, who travels to her clients and does their makeup in their homes. She does not make a lot of money and her father has recently lost her job. When she hears a phone message at at client's house about a psychological study that is recruiting subjects, she decides that if her client isn't attending, she will go instead. The study is about morality and ethics, and she has not idea what she is in for. This decision changes her life.

I do not want to share anymore about the plot because you need to discover it for your yourself. This was a gripping psychological suspense novel with a great storyline, excellent characters, and twists and turns that kept glued to the story. It was dark and suspenseful. There were unreliable narrators, interesting and unlikable characters, and a creepy story of obsession, without violence. There is obviously some mental health issues with some of the characters, and one who preys on innocents for her own, selfish reasons. It was a story about love, anger, betrayal, morality, and obsession. One thing I learned is that you need to make sure you read the fine print before signing anything. I read this book in one day, because I wanted to find out what was going to happen next. Definitely a page turner.

After reading their first book, I was looking forward to reading this one. Jessica signs up to be a participant in a psychology study. She pretends to be someone else who was asked because she desperately needs the money. The questions become very personal and invasive as Jessica starts to question herself and how far she will go. An invitation from the person in charge of the study leads to even more personal tests. Jessica soon wonders how she will escape when the person you are trying to escape knows your deepest secrets and isn’t afraid to use them. An intense psychological thriller that I couldn’t put down.

I wasn't sure what to expect when going into this book. It had been on my TBR list for a while and I knew that I needed to read and review it. So, I dove in, without even reading the synopsis and refreshing myself on what the story was about. It was honestly kind of fun because I had forgotten what it said and it was neat to discover the different twists and turns with no idea of what the story was or who the characters were. I hadn't even read the previous book by these authors so I was going in completely blind.

That being said...

This book was pretty darn awesome. The differing points of views was a really cool quality as it gave a deeper insight to the character of of Dr. Shields. At first she's presented as an apparition-type character. She's there, with heavy influence, but we know absolutely nothing about her or what her role is in the story. Once we do get to know her character, we get to one of my favorite parts of this book. Her character. Her personality and the way she was written was so clinical and odd that you couldn't help but like her even though she makes you slightly uncomfortable. The ease in which she controls all situations of those around her and speaks as though she and her actions are those of someone else, someone that she's observing, is very unsettling and makes for a super interesting contrast to Jessica's normally average, though no less interesting, character.

The lengths that Dr. Shields goes to in order to complete her "study" and the true goals behind her charades is so deliciously twisted that there was no way I could put this book down. I had to know what was going to happen next and what he obsessive mind would come up with. This book was awesome and I would honestly love to see it as a movie.

Thrilling story with a plot that kept me turning the pages, really well written with great characters. Highly recommend to everyone who is a fan of this genre.

Just like 'The Wife Between Us', An Anonymous Girl was very well written. It was intriguing and I was very quickly drawn in and could not put the book down until I was done.

I loved this book! Thank you NetGalley for the ARC. I read this book at the beach and it was a perfect beach read. There were a lot of twists and turns and when I thought I had it all figured out, I realized I didn’t, which had me guessing right up until the last page. Highly recommend for those that enjoy suspense books, I’m really excited to read more from this author.

This one kept me completely intrigued while reading, and I wanted to know what happened...but there was no huge explosive, make me gasp ending. I also didn’t particularly feel connected to any one character. They were kind of vanilla. It’s sad because I truly felt this book had amazing potential. I mean, I came up with all kinds of twists in my head that I was waiting to see if it would happen...but, alas, it didn’t. I’ve been told the authors’ other book, The Wife Between Us, is amazing. I plan to read it soon and hope I love it. This one was just a bit of a let down for me.

Thanks to the publisher and authors and NetGalley for the arc I received.

**3.5 stars

I loved the first half or so of this book. The beginning was so intriguing with figuring out the purpose of the study and getting to know the characters. But it kind of dragged on. I also found Jess to be a bit annoying and unlikable, as demonstrated by the ending. However the mystery behind Dr Shields purpose and to see how the story ended kept be turning the pages.

It was a pretty good read though overall.

A crazy moral testing book involving intrigue, betrayal, cunningly twisted scenarios and a protagonist in the midst of it all who will do anything to get to the truth and the reason she is being played!

Reminded me a bit of that Blake Lively and Anna Kendrick film.

Special thanks to Netgalley and the Publishers for this review copy.

Was excited to get to review this book. It draws you in for the first few pages and it keeps you wanting more. Fast read and loved the ending. Thanks for the opportunity to review this title. This is their second together hope to see more.

From the amazing author team that wrote The Wife Between Us comes another high stakes thriller that will leave you racing to finish.
An Anonymous Girl reads like the ultimate cat and mouse game, leaving you constantly questioning who is chasing who. Jessica, a struggling makeup artist, happens to see an ad for a paid psychological study about lying and honesty while out on an assignment. From the initial session, alarm bells are raised, but desperate for money, Jessica continues the study, eventually meeting the study's lead, Dr. Shields. The professional barrier between the two women gradually fades away as they become more and more immersed in each other's lives, with secrets becoming apparent on both sides.
I read this book in less than 24 hours as I became consumed with an intense desire to see what would happen. Unfortunately, I cannot divulge much more of the plot or the strengths and weaknesses without somehow giving away or hinting at one of the many, many twists, but this was a standout book for me. As I remembered being a young, struggling twenty something, I deeply identified with Jessica and remembered all too well my own days of signing up for studies in hopes of some extra cash or other perks (like a free lunch). Tight writing and expert plotting with relatable characters and a mostly satisfying ending make this one a five a star read.

Thank you to Netgalley and the publisher for a free advance copy. This did not impact my review.

Yiiiiiikes what did I just read (in a really good way)?!?!? I was 110% enthralled with this book from start to finish, and I have no idea why I waited so dang long to pick it up. Off to find The Wife Between us now....

Unfortunately, I can't finish this book. This book is suspenseful, but I realized that I didn't care about the characters at all. Characters are what make me want to keep reading, and unfortunately, this fell flat for me. I wasn't impressed with the writing, nor was I impressed with the plot. The blurb of this book sounded fascinating, but I wasn't impressed with the execution.

This book was amazing! I read their previous book, and liked it, but this one was so much better. The twists and turns held me captivated to the page long into the early morning hours. I highly recommend this book.

I don't know what it is about these two authors when they decide to collab on a story, but they make suspenseful book magic together.

The book starts off different then any other book I have read and that drew my attention immediately. I have read a lot from this genre so not much surprises me but the premise was different and intriguing. Dr. Fields and Jessica seemed like they couldn't be more different, but by the end I wasn't so sure.

Each chapter your getting alternate POV's of Dr. Fields and Jessica in the present. While your getting inside the head of each narrator, not all is revealed to the reader, much like The wife between us. I love this way of a plot unfolding and this duo collabs so well together, you never feel a break in their storytelling or any plot holes. The suspense is a slow build that keeps you wanting more.

I look forward to Greer Hendrickson and Sarah Pekkanen creating more best sellers in the future. Their flow in storytelling is effortless.

**I was given a copy by netgalley for my honest review **

When struggling makeup artist Jessica Farris signs up for a psychological study on ethics and morality, she thinks all she’ll have to do is answer some multiple-choice questions, collect her $500, and leave. But when the questions grow more intense and invasive, and the study “evolves”, as Dr. Shields puts it, Jessica begins to feel as though Dr. Shields may know not just what she’s thinking, but also what she’s hiding.

On one hand, Jessica is comforted by the weight lifted from her after confessing so much about herself to someone behind a computer screen. On the other, as the study continues, Jessica grows more paranoid about what’s happening in the real world and what’s another one of Dr. Shields’ experiments. Just what exactly does she know about this Dr. Shields anyway, and can Jessica actually trust them?

A gripping story about obsession and jealousy, An Anonymous Girl was, for me, the perfect blend of You and Gone Girl. Told from alternating points of view, from Jessica and Dr. Shields, readers will be caught up in the game of mental chess the two characters are engaged in, unsure who they can trust or what turn the story is going to take next.

And ultimately, even days after finishing the book, I’m still wondering about the same questions posed at the end of the book: was it all worth it? Do the ends ever justify the means? Can anyone ever really change? What boundaries are you prepared to cross — for love, for security?

I had such high hopes for this novel and was so excited to read it, but sadly, this one fell short for me. I'm not sure why, maybe the pacing and structure of the writing, but I was bored to death. I loved the premise of this novel and found the plot and characters to be unique, unfortunately, both Dr. Field's and Jess just didn't excite me. I have no idea how to pinpoint what exactly my issues were and apparently, based on other reviews, I am in the minority. I didn't experience any major suspenseful or thrilling twists while reading it, but instead, found almost all of the "big moments" predictable.

The first 60-75 pages were intriguing, but after that mark, it dragged on and on for me personally. I don't read thrillers all of the time (probably 2030% of my reading), but the ones I love are the ones that are full of surprises and An Anonymous Girl had almost none.

"Doubt surrounds even the most banal of explanations.
This is the legacy of infidelity."

An Anonymous Girl tells the story of Jessica Farris, a young woman who agrees to participate in an anonymous study about morality and ethics. She thinks it will be simple – show up, answer some questions, get paid, leave – but Dr. Shields shows an interest in her and wants to continue the study beyond the walls of the testing room. These studies show an increased manipulation of Jessica as she is told how to dress and how to act in various settings. It isn’t long until she doesn’t know who to trust – she doesn’t even know if she can trust her own thoughts as truly her own or as those of Dr. Shields.

I love a good story about an unreliable female narrator, especially one where she is in her twenties as that is more relatable, but it felt almost too like their previous novel, The Wife Between Us. I think I’m noticing a pattern to the authors’ approach. Not only are both of the main characters unreliable as narrators, but there is a distinct formulaic feel in the format of the story itself. In both books, every other chapter jumps between the two central narrators; in The Wife Between Us, we alternate between Nellie and Vanessa, while in An Anonymous Girl, we jump between Jessica and the mysterious Dr. Sheids. In the first half of the book, there is a build-up to a “big reveal”; I am notoriously bad at figuring out reveals in thrillers before they happen, but I was able to figure out both in advance. The second half of the book is more fast-paced as more twists and turns are introduced, leading to a conclusion that is more subtle than the initial “big reveal” (and, for me, unexpected in both cases).

I honestly didn’t enjoy An Anonymous Girl as much as The Wife Between Us, though from the description I was expecting to like it more. Maybe I wasn’t in the right mood for a thriller, or maybe the authors’ formula felt a little tired in their sophomoric book. I plan on reading the next book by these authors, but I am not waiting as eagerly as I was for this book.

Thank you to NetGalley and St. Martin’s Press for an advanced copy of this eBook in exchange for an honest review.

I will say that I was not a fan of their first book. I did thoroughly enjoy their writing style, so I wanted to give them a chance to get better. It was better. However, I did pick up on the twist early on, so that was majorly disappointing. I still absolutely love their writing style and I will still pick up their next book happily, just knowing that I will at least fairly enjoy the journey they give me.
