Customer Reviews


If you read only one book this year, make it this one! An incredible debut that tells the tale of deceit and the impact on a family. Well worth a read.

Good Movie. Material

This is not my usual genre but the blurb sounded intriguing and I am so glad I decided to read it. It was obvious to the reader that she had been subtly manipulated for years but when her work saw her closing in on a Russian sleeper cell it was scary how quickly the tables were turned on her; events escalated and she got sucked into a downward spiral. The book was extremely well written, I became paranoid, jumpy and uneasily aware of how events like this could truly happen. Highly recommended read.
I received a complimentary copy of this book from NetGalley. I was not compensated for my review, and I was not required to write a positive review. The opinion expressed here is my own.
