The Last Child by John Hart

In the year since his twin sister was abducted, Johnny Merrimon's life has fallen apart: his mother's a mess, his father took off, the police haven't found Alyssa, and his mother's rich, predatory boyfriend is abusive in every sense of the word.

Johnny's taken matters into his own hands. He draws the boyfriend away from his mother by throwing rocks though the window back at his mansion. He stalks local pedophiles and records their habits in search of his sister. Since God has let him down, Johnny's turned to Native American and Celtic rituals for strength and protection.

This book was completely engrossing. I haven't even begun to touch on the storyline with this description; there are about five related stories going on. It wasn't gory and horrifying, more a psychological thriller with multiple twists and turns.

I will be a bit critical of the narrator, though: Scott Sowers over-enunceates to the point of distraction sometimes. I'm not sure if he just needs practice as a narrator, or if he's just not cut out for this kind of work. Sometimes he's flat, sorta like a kid reading aloud without comprehending what's in front of him.
