If there were 10 stars as a rating, this book would have merited it. I was enthralled from the very first page. Jessica has a job she enjoys, working for a cosmetics company, but then she stumbles upon an opportunity that sounds intriguing to her. She gets into a research study run by Dr. Shields and as she desperately needs the money offered for the study, she tries to be as honest as she can be, with her answers. Then the questions get more personal and Jessica get entangled in a way she never imagined. Is this just a research study or is it more than it would first seem. The story flows and takes you along with the totally believable characters. This is a truly intriguing narrative. I am hoping that the authors will write another book soon.
