With the rift closed for the season and no more monsters to fight, Daelin Long gets bored as librarian in the podunk town of Settler, Oregon. A job interview and her brother€s arrival present a tempting opportunity to escape, until her brother and her best friend, a ghost, disappear.
While Daelin searches for them, more mysteries pile up: dead people coming back to life, portraits of the town founders replaced with strange white trees, and people on the other side of the rift returning. It€s impossible. The portal that allows monsters from other universes to come to Earth is sealed until next summer.
The Rifters, a secret group protecting our world, believe the troubles are nothing more than the tantrums of an offended ghost. Daelin disagrees. If she€s right, the evil hell-bent on destroying Earth has new technology making the rift more deadly.
Before the monster summons the next apocalypse, Daelin must find it and destroy it.
