Fourteen-year-old Bobby Pendragon and Spader from the planet Cloral journey back in time to 1937 New York City to uncover a plot by the evil Saint Dane.

Fourteen-year-old Bobby Pendragon, having learned he is a Traveler--someone who can ride "flumes" through time and space--is soon off to the alternative dimension of Denduron where he teams up with Loor, a girl his age from the warrior-territory of Zadaa, in an attempt to save the gentle Milago people from slavery.

"A final showdown is in order between best friends Marshall and Cooper and the terrifying villain Damon, who's more determined than ever to break down the walls between the worlds of the living and the dead. Marshall is forced to make a brave and shocking choice when the battle is on the line, and he and Cooper might be rewarded with help from someone quite unexpected"--Provided by publisher.

Sixteen-year-old Marshall Seaver is expecting a boring summer when his best friend goes away, but instead he finds himself haunted--and hunted--by ghosts that want something from him which he cannot decipher.

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

With Saint Dane seemingly on the verge of toppling all of the territories, Pendragon and Courtney set out to rescue Mark and find themselves traveling--and battling--their way through different worlds as they try to save all of Halla.

Fifteen-year-old Bobby Pendragon places himself, his friends, and the people of Halla in danger in order to protect the territories from a mysterious plague.

The demonic Saint Dane attempts to take over Loor's home planet of Zadaa, opposed once again by the teenaged Pendragon and other Travelers.

Cooper Foley, who has a knack for getting into trouble, ends up in the middle of a border war between the worlds of the living and the dead, trying to find out about the mysterious Morpheus Road.
