All You See Is Light — Jerry J. Davis

Seventeen year old Tom Harrison lost his parents in a plane crash under mysterious circumstances, and has gone to live with his swinger aunt and uncle in a small costal town nestled between an oil refinery and a golf resort. Feeling alone and lonely, and struggling to deal with his loss, he finds himself in a weird world of bullies, horny MILFs, and someone who may or may not be an actual angel.

Is she there to save him, or is he there to save her? Neither of them know because ... well, she can't remember!

Maybe they're supposed to save each other?
