Symbiosis — Tim Curran

When Flynn was sixteen, he was a new kid in a new school. At first, he was ignored. Then he was bullied, tormented, and beaten. Chad Reese offered him a way out. He introduced him to Toddy and Bones. They made Flynn's enemies their own. Before long, he was the most popular kid at school. But there was a price. When he wouldn't pay it, they took something he loved. Now, thirty years later, Flynn is rich and successful. Everything he touches seems to turn into gold. Until he comes back home to discover that the payment for living the good life has been long overdue.
