In the tar-melting heat of a suburban summer, everyboy Jules, athletic and handsome Chris, and oddball Corey (he laughs at gravel and anticipates zombie attacks) have lived side by side for most of their lives. Behind their backyards is a ravine through which flows a modest river. This familiar territory is by turns comforting and terrifying.When a tornado brings down a big maple tree, the boys make a raft of the branches and set off downstream. After all, at thirteen they are old enough to take a day trip by themselves. On their way, the boys meet with a series of adventures that are funny at first glance but resonate deeply. They rescue a diabolical dog, confront a hydrophobic gang, and survive a waterfall. They are bombarded by bicycles, hoodwinked by hobos, and bewitched by bikinis.
