Fourteen- year-old Bobby Pendragon has it all; he's smart, popular, and a star basketball player in quiet Stony Brook, Connecticut. But a visit from Uncle Press soon topples all of that as Bobby learns that he is a Traveler, someone who can ride "flumes" through time and space.

Each of the Travelers returns home to learn the truth about their origins before being reunited for a final, ineveitable confrontation with Saint Dane, whose efforts to control Halla are destroying its very foundations.
