In the near future, in the Epcot of Walt Disney's imagination, sixty thousand people live in a CommuniTree surrounding the forward-looking Walt Disney World theme park. Five unique families are among the residents—and some of the parents were once known as the Kingdom Keepers. Their identities are carefully guarded in order to raise their children without special treatment, most of the Kingdom Keepers work for the Walt Disney Company, and have settled into "ordinary" and rewarding lives.

With the defeat of the Overtakers behind them, the five teenagers known as the Kingdom Keepers should be celebrating. By all accounts they saved Disneyland from certain destruction. Why then did their mentor leave one last puzzle for them to decipher? The Keepers must solve a puzzle of the past, or be crushed under an evil that makes the Overtakers seem like gentle souls.

When Amanda travels east to Orlando on a hunch, she's met with the worst news possible. Kingdom Keeper Finn Whitman is missing. Calling on her own gift (she's telekinetic), her sister Jess' ability to dream the future, and their fellow Fairlie Mattie Weaver's unexplained ability to read minds through physical contact, the three gifted girls must navigate treachery, deception, and the stubborn, unwilling parents of the missing Keepers if they're to save their friends.

Even though ­thirteen-­year-­old Marcus Kanenas is confined to a wheelchair, he sees himself as a survivor and a dreamer. In fact, his favorite dream is of a world far away, a world where magic is as common as air, where animals tell jokes, and where trees beg people to pick their fruit. He even has a name for this place - Farworld. When Marcus magically travels to Farworld, he meets Kyja, a girl without magic in a world where spells, charms, and potions are everywhere.

Eleven-year-old Josh and 12-year-old Amanda just moved into the oldest and weirdest house on the block - the two siblings think it might even be haunted! But of course their parents don't believe them. You'll get used to it, they say. Go out and make some new friends. But the creepy kids are not like anyone Josh and Amanda have ever met before. And when they take a shortcut through the cemetery one night, Josh and Amanda learn why.
