It starts as an end-of-junior-school sleepover, but when Athena, Hal, Peter and Erin stumble across a missing boy, deep in the forests surrounding sleepy Clegg, Texas, they discover a world of sorcery and untold power. So begins a new life with the Dissonance, under the tutelage of Professor Elijah Marsh. Twenty years later, separated and broken by their experiences, the friends are pulled back to Clegg for the anniversary memorial service at the towns high school. Each carrying their own trauma, they come together once more to confront the legacy of their actions, and the monsters they failed to bury. Hurled onto a collision course with the apocalyptic events of their past, Owen, a young man trapped in service to a murderous entity, and several lifetimes of mistakes, three unsuccessful adults and one frightened teen are all that stand between reality and oblivion.
