Hit and Run [PDF ebook] 

Fifteen-year-old Mike Mc Gill has lived with his Uncle Billy since his mother’s death. Only ten years older than Mike, Billy loves to party, and he doesn’t pay much attention when Mike starts getting in trouble. But nothing gets by Mike’s history teacher, an ex-cop named Riel-especially not long-hidden information about Mike’s mother. Her death might not have been an accident after all!
