The Serpent King by Jeff Zentner

Dill has had to wrestle with vipers his whole life at home, as the only son of a Pentecostal minister who urges him to handle poisonous rattlesnakes, and at school, where he faces down bullies who target him for his father’s extreme faith and very public fall from grace.

The only antidote to all this venom is his friendship with fellow outcasts Travis and Lydia. But as they are starting their senior year, Dill feels the coils of his future tightening around him. Dill’s only escapes are his music and his secret feelings for Lydia, neither of which he is brave enough to share. Graduation feels more like an ending to Dill than a beginning. But even before then, he must cope with another ending- one that will rock his life to the core.
