This is an amazing book! This is my second book by these authors and it did not disappoint. 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. The story kept me questing until the end of the book. Just when you think you have it figured out, a new twist comes in. I would highly recommend this book to people who enjoy thrillers and trying to figure out the plot. This is not a light and quick read but perfect when you want the extra thrill.
