Gangs of Athol - Clark Graham - Bog

Only one week after finishing sixth grade, Billy's summer was already doomed. He'd been kicked out of his bicycle gang, leaving him no friends to hang out with. In a small North Idaho town, what else could he do? On top of that, his mother was more secretive than ever. Billy feared she had a boyfriend. How else to explain her hushed late-night phone calls? And who was the man watching their house from across the street? If Billy had a father, he'd feel safer, but he didn't know who he was. His sister, Loretta, fell for the story about the stork. As the summer progressed, mysteries increased, including a mystery man parked outside the house every night and an evil looking stranger riding a motorcycle who asks about his family all over town. Mother promised "all will be revealed" when Billy is a teen, causing Billy to dread his upcoming birthday.
