Sanctum

In this haunting, fast-paced sequel to the New York Times bestselling photo-illustrated novel Asylum, three teens must unlock some long-buried secrets from the past before the past comes back to get them first. Featuring found photographs, many from real vintage carnivals, Sanctum is a mind-bending reading experience that blurs the lines between past and present, genius and insanity, perfect for fans of the smash hit Miss Peregrine's Home for Peculiar Children.
Dan, Abby, and Jordan remain traumatized by the summer they shared in the Brookline asylum. Much as they'd love to move on, someone is determined to keep the terror alive, sending the teens photos of an old-timey carnival, with no note and no name. Forsaking their plan never to go back, the teens return to New Hampshire College under the guise of a weekend for prospective students, and there they realize that the carnival from the photos is not only real, it's here on campus, apparently for the first time in many years.
Sneaking away from sample classes and college parties, Dan and his friends lead a tour of their own—one through the abandoned houses and hidden places of the surrounding town. Camford is hiding a terrible past, and the influence of the asylum runs deeper than Dan ever imagined.
