Jenna is 18 and on her own for the first time. She lives with Merle and Caro, two of her closest friends. When a young woman is found murdered, the girls are concerned but continue their lives.
Until Caro goes missing. Before her body is discovered, in the same way as all the other girls, Jenna and Merle start to question what was going on with Caro's new boyfriend. And their determination to find him.
Nate is sure he's been careful, but he is worried the police are on to him. Caro seemed like the perfect girl but she disappointed him. And now he has new prey...Jenna.
The book was originally written in German, then translated to English. It took a while to get into, the perspective changes from various characters often, and it switches from 3rd person to 1st. About halfway through it picks up, but I'm not sure how much it will appeal to teens.
