I adored We Were Liars (heartbreaking, I literally read it in one sitting and cried at the end). I had high hopes for Genuine Fraud and I wasn't disappointed. 

This is a psychological thriller with a pathological liar at its heart.  Jule is the protagonist (or antagonist if you want to be fancy) and she has the ruthless survival skills of a trained assassin. Except, she isn't an assassin but a girl who has charmed and wormed her way into the life of one of New York's social elites, Imogen. 

Jule wants what Imogen has and she will do anything to get it. 

Anything.

E. Lockhart's writing is alluring and although Jule was highly unlikeable (sorry, I'm pretty sure you aren't meant to bond with her).Her motives are murky and her cut throat survival instincts were both horrifying and impressive.

Genuine Fraud is both a "feminist thriller" according to Lena Dunham, and a joy ride into the life of the rich and famous. You will feel like you are in a washing machine of deception (literally I got so confused at one point) but stick with it, the ending will have you gripped.
