You Don't Know About Me — Brian Meehl

Sixteen-year-old Billy Allbright is about to bust out of his sheltered cocoon and go on a gonzo road trip. He just doesn't know it yet. His ticket to freedom? A mysterious Bible containing two resurrection stories. The second is about a man Billy's never met, and who is supposedly dead: his father.
But the road to a risen-from-the-grave dad, and the unusual inheritance he promises, is far from straight. Billy zigzags across the American West in a geocaching treasure hunt. When his journey includes a runaway baseball star, nudists who perform sun dances, a girl with neon green body parts, and con artists who blackmail him into their "anti-action movie," Billy soon realizes that the path to self-discovery is mega off-road.
