First of all, the cover and the title took my attention. Synopsis only warms up the atmosphere. After reading a sample of the book, I was left curious and intrigued, puzzled. The plot seems more complicated than I could think in the first place. Thinking about the psychopath personality, I forgot that this theme stands for the person who does not understand and have feelings. I am very absorbed in the story. I want to know what has happened before Carolyn and Mark meet and what will happen even after! Written very well, narration in a first-person - what I love! I was surprised to discover that it is a true-crime story. I need to read this book.
