Wow this book has so many twists and turns it kept surprising me! I thoroughly devoured this book and loved the characters. Jess is a makeup artist and joins a research study with Dr. Shields. They both tell the story in alternating chapters. Both have so many secrets from the other and it is quite a dance for them to keep them from the other. I highly recommend this book as a thriller and one that will keep you reading until the very end. I received an advanced readers copy from NetGalley and St. Martin's Press. All opinions are my own.

Intriguing and mysterious thriller about a psychiatrist, her husband, and a young woman caught in a psychological web she must escape in order to survive.

Jessica needs money to help her parents with the medical bills for her younger sister. She finds her into a psyche study being researched by a Dr. Shields. All she is interested in is the $500 she will receive for two days, two hours each day, of questions and answers. Jessica is totally unaware what the consequences will be... she is just seeking that precious money she desperately needs.

The study deals with ethics and morality. The questions require complete honesty, although they are deeply intimate and invasive of her personal beliefs and actions. As the study unfurls, Jessica finds herself questioning her decisions more and more. Some of the real-life scenarios she is expected to enact lead her to begin questioning the purpose of Dr. Shields' study. The complexity of her interaction with Dr. Shields and the situations she is placed in the middle of, send alarms to her protective side. As she begins to unravel the reason why she has been chosen for this study, she recognizes finally she is caught in a web that can mean her life is in danger.

This book was very entertaining and thrilling. I gave it 4 Stars because for a seasoned writer, this book should have a stronger ending and no mistakes in the plotline. For instance, in Part One much is made of where Jessica will sit during her visit to Dr. Shields home for the extraordinary meetings. Much is made out of the fact that she sits in the chair. Later on, the author states that Jessica continues to sit in the love seat like the first time, which is not true. It is an obvious oversight and should be caught by any editor worth their weight. Please correct this. For a psyche thriller, details are important. The decision Dr. Shields makes at the end is questionable to me. I think it breaks character. Just my opinion. Overall, this is a great book readers will enjoy.

I am voluntarily reviewing this book. I thank the publisher for sharing a copy with me.

It is nearly impossible to describe this book without revealing essential pieces of the plot, key elements that will be much more exciting if you are allowed to discover them on your own. It will be far easier to explain, if you are a lover of suspense/thriller talfes, why you must read this book.

The story is told in first person present. I am not normally a fan of this POV and tense, but in this story, the choices work. What makes it special is that there are two narrators, swapping back and forth, chapter to chapter. Even though the POV puts us inside each narrator’s head, everything is not always revealed to the reader. Instead, it is portioned out in slow measure, driving the suspense higher as you progress further into the book. Even right up to the end, the true motives of all the characters are not fully revealed, which enables the authors to weave feelings of danger throughout the pages, leaving us to wonder if the heroine will survive until the end.

The writing is impeccable, and there are no plot holes that could have damaged the integrity of the story. Even with all her faults, the main protagonist Jessica is likeable, and I soon found myself identifying with her questions and fears. Once I began reading it was hard to stop, and most of the book was completed in one sitting.

Bottom line: This is a tight, psychological suspense story that will periodically have you on the edge of your seat. The scariness is primarily generated by the fears (perceived and real) in Jessica’s mind, aided by the information from the second narrator. The story also examines morality and ethics, as “What would you do if…” questions quickly merge with a frightening reality. Can’t recommend this one enough. Five stars.

My thanks to NetGalley and St. Martin’s Press for a complimentary advance ebook of this title.

I enjoyed this book. Keeps you guessing til the end. Has many twist and turns along the way. My kind of book and I would highly recommend it.

If you liked the Wife Between Us you will Love this book!

Wow, you just don't know who is telling the truth but the truth will set you free. This book grabs you right from the start. You just don't know who is telling the truth until the very end.

It is about a makeup artist, Jess, who does not have a lot of money and is trying to help out her family. Her sister is disabled and she feels that it was her fault and has carried around that guilt for many years. When Jess is at a clients house she hears about doing a study for money, as she is always short on cash.

The study seems pretty simple at the beginning but then she gets sucked into the life of the doctor.

I can't share anymore than that as I will ruin the book.

A great read!!

An Anonymous Girl has claimed the title of my favourite thriller of 2018. Bold claim when we have around 8 weeks left of 2018 but I found this book so addictive and managed to polish this off in just two sittings.

When Jess, a struggling makeup artist in New York, gets involved in an experiment about morality run by an elusive psychiatrist, she is paid handsomely for her answers. However, she soon finds herself in a game of psychological cat and mouse and left wondering what she has gotten herself into.

The pace of the book was perfect. It was well written and although you could see the twists coming, it built up a good level of suspense which made for an enjoyable read. I found the book engrossing and extremely clever. A must read that I haven't shut up about and convinced a few friends to pre-order.

Thanks for allowing me to review this, St Martin's Press!

"An Anonymous Girl" begins with Jessica (Jess) who does make up for a living through the company Beauty Buzz in New York City. She had been working on broadway shows before she was assaulted. With the current job, she makes enough to maintain her lifestyle plus send some home to care for her younger sister, who has traumatic brain injury and needs lots of care. While doing a client's make up at the college, she learns that she was invited to do an ethics study which would pay $500 for a couple hours. Learning that the client is unlikely to go, Jess decides to go in her place.

The ethics professor, Dr. Shields, is watching as Jess enters the study. She fits the demographic profile but lied in order to enter the study- one about ethics. Dr. Shields invites her back to make sure she would be the person she was looking for. After she does, Dr. Shields invites her to participate in further, in-person experiments. Unable to pass up the money, Jess decides to give it a try- after all, she can exit the study at any time.

However, as things begin to escalate, Jess is unable to extricate herself from Dr. Shields and her life begins spiraling out of control. Will Jess be able to unravel the past- the previous study subject who died- and outmaneuver Dr. Shields before it is too late?

This book was fast-paced and I felt just as confused as Jess. The book is told in alternating points-of-view between Jess and Dr. Shields. We get pieces from each, but neither is explicit about the information they have nor where it could lead. We must read and unravel the tangled web ourselves. Jess was easy to like, and she is the one we really feel for when reading the story. On the opposite site, Dr. Shields makes an excellent villain, and we are never totally sure of her motives. On one level, we do get the basic motivation, but it's more complex than it might seem and her feelings about the other players are equally complex.

This was a really quick read for me, as I devoured each chapter as it leads to the finale. The pacing of the writing was really perfect with a slow build and crescendo that follows the storyline perfectly. I was surprised that no one had noted any ethics violations of the professor earlier (for instance, involving subjects in further studies without informed consent- but then again, the secrecy and lies might take care of people not knowing who to turn to). There are some pieces where it becomes clear that the repercussions of normal reactions might be too great to follow these paths (e.g. going to police), but it still may have been worth a try (I would think someone in a situation might try something). That said, I could suspend the disbelief to really enjoy the thriller.

Overall, this was a fast-paced and intense psychological thriller, and I enjoyed the read. Please note that I received an ARC from the publisher. All opinions are my own.

What will you do for money? Riveting page turner about a makeup artist with some secrets, and a study that is life changing. Jaw dropping from start to finish!

Spellbinding! Compelling! The author weaves a magic of dramatic psychosis that is heart pounding. Each turn of the page draws you deeper into the web that Dr. Shields is creating for Thomas and Jessica. The information is slowly parsed like a dripping spout leaving you desperately wanting to skip to the next page. Brilliantly written!

No one can be trusted because EVERYONE is lying. If you’re looking for a psychological thriller full of shocking twists and turns... here ya go! This book will suck you in and play with your mind until the Very. Last. Word.

Jessica Farris is struggling to make ends meet. She signs up for a study on ethics and morality for the money. As Jessica participates in the study the questions become more invasive and she begins to question what is real. Exactly what is the motivation of the psychologist heading the study?

This book will grab you from the first page and not let you go. There were two issues I had with the book. One was it is written in the first person, which I don’t usually like. Also the book was written from multiple points of view which was a little confusing at the start. In spite of that the book was tension filled and there were enough twists and turns to keep me turning the pages. Thank you to net galley for an advanced readers copy.

What another great read from authors Greer Hendricks and Sarah Pekkanen. As a huge fan of their debut book, I was so excited to read this next one. I love the alternating viewpoints and their writing style(s). This dark thriller was hard to put down. While there weren't as many twists in this book than their previous one, it was still enjoyable and suspenseful. I would definitely recommend!

Strapped for cash, Jess takes advantage of an opportunity for quick cash by participating in a research study. What starts off as a seemingly innocent relationship, Jess discovers herself roped into a game of manipulation.

A quick read with twists and turns, some being predictable and a few not.

This is an amazing book! The story kept me guessing until the very end. Jess is involved in a ethics study and the leader of the study takes a particular interest in her. The leader asks Jess to get involved in real life situations and it becomes very interesting. The chapters are sometimes told from Jess’s viewpoint and then the leader of the study. I would highly recommend this book!

This is my second book by Sarah and Greer. I absolutely loved the wife between us, so once I saw this one I knew I had to have it! I was so excited when I got accepted for the arc.

I'm a total thriller girl its the only genre I read, this one definitely is true to the genre. It keeps you guessing throughout the whole book. I kept telling myself just one more chapter. I was totally sucked in right from the beginning! Who doesn't love a book that's great right from the start? The story is told is 2 different POVs and the chapters flowed seamlessly. I would say that it was a quick read just for the fact that it was such a good book you can't put it down. It was definitely a fun creepy read as well as suspenseful, thrilling and keeps you on the edge of your seats. I would definitely recommend this to people who love thrillers and love the suspenseful feeling while reading a book.

I was so excited to read this book since I loved The Wife Between Us! I enjoyed this book almost as much as the first but it wasn’t as twisty as I wanted it be. All in all a really good book.

Loved how the book was written in 2 perspectives. It kept me guessing and was very entertaining. A great, fast read!

3,5 Stars rounded to 4 Stars

I was tempted to read this book after reading the review of one of my Goodreads friends, i didn't read The Wife Between us (i still don't plan to read it), so i didn't know exactly what to expect from this book. It was however an agreeable surprise.

Jessica Farris joined a study on morality, conducted by a mysterious Dr Shields. What she thought to be only a few survey questions to answer turned out to be much more that, as Dr Shields slowly took over her life and stripped her of all her secrets and as she found herself entangled in a net of lies, deceits and danger.
The book is divided into three parts, i think i read the first part without a break. The idea was surprising and the execution was good, as there was an alternation in chapters between Jessica and Dr Shields telling the story, the chapters with the Dr were actually creepy sometimes, but i enjoyed them the more for that.
I liked the story, the feeling of not knowing which of the character to trust and which one is more dangerous than the others. Maybe it is all this anticipation building all along the book that made the ending rather disappointing. I don't know how to accurately describe the feeling, it was a logical ending, one we would expect; but, the way it was written off in a couple of pages made it seem too easy, almost banal. I know i am not conveying the right "feeling", let's just say, that i stayed up late at night to finish it and when i got to the end, all i thought was "That's all ??!!!!!"

One thing i want to add is related to the cover, at first glance i thought it was only a new edition of the first book of the authors "The Wife Between us" using a new Color. I know it somehow fit the story, but it didn't distinguish itself from the first book.

An Anonymous Girl started out strong and suspenseful till the end. If you like psychological thrillers, this book does not disappoint, it had you guessing all the way through the book. Thank you NetGalley for the advanced copy.

This book started off strong but it started to fall flat before the 50% mark. I’m not sure what happened but I found myself very confused and I almost did not finish. I forced myself to look at other reviews and most are 4-5 stars. I mean, I couldn’t be the ONLY one not enjoying this book so i kept going. Oh I’m so glad I did. All of a sudden, things started to make more sense and I found myself wanting to devour it until the end. 4 stars for me but only because of the confusion I had through the beginning. Thanks to NetGalley and the publisher for my advance copy for my honest review.
