A friend gave me a book calendar and I can't tell you how many good books I've read that were recommended on it. This was one of them. We find out immediately that Michael is in jail, that he doesn't talk, and that something really awful happened to him when he was eight.
He decides to write about his life and alternates between his early life and his life of crime. He has two gifts: he can unlock anything and he's a decent artist. He's also a decent person.
I gulped it in two days!
