Avalon by Nell Zink

Bran's Southern California upbringing is anything but traditional. After her mother abandons her and joins a Buddhist colony, Bran is raised by her 'common-law stepfather' on Bourdon Farms - a plant nursery that doubles as a cover for a biker gang. She spends her days tending plants, slogging through high school and imagining what life could be if she had been born to a different family.

Then she meets Peter - a charming, troubled college student from the East Coast - who launches his teaching career by initiating her into the world of art. The two begin a seemingly doomed long-distance relationship as Bran searches for meaning in her own surroundings. She knows how to survive, but now she must learn how to live.
