The mystery is so good, although by the end of this first book you can deduct who is the killer. But then even more twists and turns makes it very interesting….But, the main female character is so stupid and intense that all I wanted to do was punch her. Her constant fight and actions are so exaggerated and psychotic that I do not understand why the main male character even likes her. Every time she is told something, she repeats it as a question, shouting hysterically EVERY SINGLE TIME… She is insufferable. She gets better by the end, but she has no redeeming qualities to have Santos fall for her, she is just very stupid.
