Luke Dellar, age twelve, is weary of his flip-flop life. He flies to his father's house in San Diego one month and back to his mother's house in Seattle the next. He's even more tired of taking pills for his hyperactivity that has worsened since his parent's divorce. A solution to his flip-flopping, pill-popping life? Run away and hike the Pacific Crest Trail, a 2650 mile, five-month journey from the Mexican border to the Canadian border.
