The Door at the End of the World

Fantasy meets sci-fi, in this exciting, charming new story from the author of THE WORLD’S GREATEST DETECTIVE.

There’s no signpost to mark the end of the world, so you need to know what you’re looking for: a gatehouse, a garden, a tall brick wall overgrown with flowering vines. . . and the door. You’ll have to wait a while, too, since the Gatekeeper likes to take her time. Traveling from one world to the next isn’t something a person should do on a whim, and she wants to make sure you mean it.


What begins as a rather unremarkable Thursday quickly turns to disaster when Lucy, the Gatekeeper’s deputy, discovers that her boss has vanished, the door connecting Lucy’s world to the next world over is broken—and it might all be Lucy’s fault. To save the Gatekeeper and set things right, Lucy must break the rules for the first time ever and journey with an otherworldly boy, a suspiciously sneaky girl, and a crew of magical bees into the seven worlds beyond her own.

But Lucy isn’t the only one breaking the rules. As curiosities and dangers gather around her, she learns she’s up against a sinister force that’s playing with the delicate fabric of time and space, no matter what the deadly costs or consequences. Lucy’s never had to save the world before—and now, somehow, she’s got to find a way to save eight of them.
