d roller coaster of an adventure" by J. K. Rowling, this New York Times bestseller is the first installment in the explosive tween fantasy series by famed Hollywood director Chris Columbus (of Harry Potter fame) and bestselling author Ned Vizzini (It's Kind of a Funny Story).

Siblings Brendan, Eleanor, and Cordelia Walker once had everything they could ever want. But everything changed when Dr. Walker lost his job. Now the family must relocate to an old Victorian house, formerly the home of occult novelist Denver Kristoff--a house that simultaneously feels creepy and too good to be true. By the time the Walkers realize that one of their neighbors has sinister plans for them, they're banished to a primeval forest way off the grid.

Bloodthirsty medieval warriors patrol the woods around them, supernatural pirates roam the neighboring seas, and a power-hungry queen rules the land. To survive, the siblings will have to be braver than they ever thought possible--and to fight against their darkest impulses. The key may lie in their own connection to the secret Kristoff legacy. But as they unravel that legacy, they'll discover that it's not just their family that's in danger . . . it's the entire world.
