A truly chilling page-turner! I was on the edge of my seat the entire time with this gritty thriller. LOVED IT! This book surprised me. I love the way Darby evolved in a deliciously dark knight kind of way. She was undoubtedly a hero, but she also had to become a monster, in a sense, to fight against the real monster. Some twists I saw coming, but it didn't make them any less awesome, and others blindsided me in the best way. Highly recommend this one to fans of thrills and chills.
