This was the most suspenseful thriller that I have read in a long time! Once I started it I didn’t want to put it down but, unfortunately, I had to keep up with other obligations. The main character, Jess, is a makeup artist struggling to make ends meet plus help her parents pay for her younger sister’s medical bills. When she sees an opportunity to make $500 by participating in a morality and ethics study, she jumps at it, even though she isn’t truthful about how she came to participate. Jess thought she would just answer a few questions, collect her money and be on her way. It becomes much more involved and the compensation increases. The story is at times dark and twisty. Highly recommend you read this when it becomes available on a January 8, 2019. Thank you to BookishFirst and St. Martin’s Press for the ARC. Now I must check out the first book by these authors, The Wife Between Us.
