Marnie Piper prepares to begin a new school year, she asks the Halloweentown Hot Witches' Council to work toward openness between Halloweentown and the mortal world. She proposes to bring a group of Halloweentown students to her own high school in the mortal world.

Two centuries in the future, when pollution has forced humans to abandon Earth in favor of cramped space stations, scientist Devon Adair hijacks a spacecraft and sets out with a band of followers in search of another planet that will offer a brighter, more normal future to children like her son, Ulysses. Joining Devon and Ulysses are mechanic John Danziger and his daughter, True; team physician Julia Heller, who has her own secret agenda; Alonzo Solace, a pilot; Yale, a cyborg; and Morgan, a craven government agent, and his wife, Bess. The voyagers find their planet, but their ship crash-lands on the wrong side of the globe, forcing them to attempt an arduous and dangerous trek to their ultimate destination, New Pacifica.

On her 13th birthday, Marnie learns she's a witch, discovers a secret portal, and is transported to Halloweentown — a magical place where ghosts and ghouls, witches and werewolves live apart from the human world. But she soon finds herself battling wicked warlocks, evil curses, and endless surprises.

The Cromwell clan lives in the real world, except for their grandmother who lives in Halloweentown, a place where monsters go to escape reality. But now the son of the Cromwells' old enemy Kalabar has a plan to use the grandmother's book to turn Halloweentown into a grey dreary version of the real world while transforming the denizens of the real world into monsters.
