Leave the lights on for this first book in a new thriller series! The author of the #1 New York Times bestseller Pendragon invites you to enter The Library, where the stories you can't finish just might finish you.

There's a place beyond this world where spirits tell their tales—stories that ended too soon, or don't end at all. It's a place for unexplainable things: mysteries without solutions. Ghosts. Boogeymen. They all have a story.

Marcus and his friends have found the key to unlock the Library. And they need to use it, because, clearly, something is up. Some strange guy in a bathrobe haunts them; fires rage and flare out in an instant; a creepy old lady shows up at Marcus's house. . . . At first Marcus thinks he's going nuts, until the terror gets real. The Library may hold some answers, but if there's an unfinished mystery, the three friends will have to complete the story . . . any way they possibly can.

"I'm not sure anyone does suspense quite like D. J. MacHale." —James Dashner, New York Times bestselling author of the Maze Runner series
