The 9th Girl - Tami Hoag

The advertisement said: "“Kovac had seen more dead bodies than he could count: men, women, children; victims of shootings, stabbings, strangulations, beatings; fresh corpses and bodies that had been left for days in the trunks of cars in the dead of summer. But he had never seen anything quite like this. . . .”
Well, it sounded promising. I had read murder stories that made me sick and from the advertisement, I imagined some kind of cruelty beyond imagination. It turned out not so new or so scary, but this book was still a good read.

Police detective Sam Kovac and his partner Liska were in the middle of a serial killer investigation. The new victim, which the press called as the 9th or the zombie, fell down from a car's trunk during a road accident. As the investigation went, the 9th victim was identified as a friend of Liska's son. Perhaps half of the book was about how hard raising teenagers. I think in the end this book was as good as Prior Bad Acts and I finished this in 2 days, which was very fast.
