I was a super fan of the wife between us, and I can already tell I will be a super fan of this novel too! I love the writing style, and how the book is formatted with the dates like a diary entry. The idea of a study hasn’t been over done so it is new and refreshing in my opinion. Coming from someone who has a degree in psychology, this book will bring in a lot of readers!! I am so excited to read the rest and see what twists the authors include!
