Fractured, by Karin Slaughter

Imagine a mother's rage as she finds her daughter dead and the murderer standing over her. This mother kills him with her bare hands. The Atlanta police have a closed case. Enter Will Trent from the Georgia Bureau of Investigation, who finds that another girl was also there, and has been kidnapped. Slaughter takes us on a wild ride and you'll enjoy each twist and turn. This is the second time Will Trent, the dyslexic detective, shows up as a character in one of Slaughter's books. He's a keeper!
