I really enjoyed this sample. I am a fan of psychological thrillers and this book has the potential to be a great one. The sample was intriguing and grabbed my attention from the beginning. I am especially intrigued by the chapters that appear to be from the POV of Dr. Shields or someone that is involved in the study. I just reread the synopsis and I am really interested in reading how the story develops, what we learn about Jessica (especially her secrets) and how it ends.
