Jess is a struggling makeup artist trying to make ends meet in New York City. She overhears a client who is thinking of turning down an opportunity to make $500 taking part in a research study and decides to go in her place. It is as simple as honestly answering questions about ethics and morality.  Ultimately the unasked questions were the spine of this novel:  what would you do for love?  And what would you do for money?

An Anonymous Girl is a roller coaster of a read. This definitely has psychological thriller written all over it.  It was creepily clinical in places and anxiety-inducing in others.  The story is written in the first person from the points of view of both the protagonist and antagonist. Although, the characters were not very likable and the Jess seemed a little too naïve at points, the story was captivating. 
The plot was labyrinthine; every twist and turn led you to another twist and turn and the authors gave you just enough bread crumbs to start to figure out what was happening but surprised with the details.   

Overall, this was a great read and hard to put down 4.5 stars.
