The Cloudkiss Killer is dead. Now a true-crime podcast is hosting a contest to find his bones. Lucy was almost the serial killer’s final victim. Carolina is a true-crime fan who fears her own rage. Maggie is a psychology student with a little too much to hide. All of them are looking for answers, for a new identity, for a place to bury their secrets. But there are more than bones hiding in the shadows…sometimes the darkness inside is more frightening than anything the dead leave behind.

A cemetery full of the restless dead. A town so wicked it has already burned twice, with the breath of the third fire looming. A rural, isolated bridge with a terrifying monster waiting for the completion of its summoning ritual. A lake that allows the drowned to return, though they have been changed by the claws of death. These are the shadowed, liminal spaces where the curses and monsters lurk, refusing to be forgotten.

Radcliffe Prep. The third most haunted school in the country, where a student disappearance isn’t uncommon and no one dares stay in the library after dark. And Este Logano enrolls with the hopes of finding her dead father. Not literally, of course. Going to her dad’s school just seems like her best hope at figuring out who he was. But then Este meets Mateo, who is maybe—probably—definitely—a real ghost. And an annoying one at that. When Mateo frames Este for the theft of a rare book from the library’s secret spire and then vanishes, Este will have to track him down or risk being expelled.

Ellingham Academy is a famous private school in Vermont for the brightest thinkers, inventors, and artists. It was founded by Albert Ellingham, an early 20th century tycoon, who wanted to make a wonderful place full of riddles, twisting pathways, and gardens. "A place," he said, "where learning is a game." Shortly after the school opened, his wife and daughter were kidnapped. The only real clue was a mocking riddle listing methods of murder, signed with the frightening pseudonym "Truly, Devious".

This trip is going to be Dylan’s big break. Her geologist friend Clay has discovered an untouched cliff face in the Kentucky wilderness, and she is going to be the first person to climb it.
