ASYLUM - Harper Collins USA

ONCE YOU GET IN, THER'S NO GETTING OUT.
For sixteen-year-old Dan Crawford, the New Hampshire College Prep program is the chance of a lifetime. Except that when Dan arrives, he finds that the usual summer housing has been closed, forcing students to stay in the crumbling Brookline Dorm-formerly a psychiatric hospital. As Dan and his new friends Abby and Jordan start exploring Brookline's twisty halls and hidden basement, they uncover disturbing secrets about what really went on here...secrets that link Dan and his friends to the asylum's dark past. Because it turns out Brookline was no ordinary psych ward. And there are some secrets that refuse to stay buried.
Featuring haunting found photographs from real asylums, this mind-bending reading experience blurs the lines between past and present, friendship and obsession, genius and insanity.

And don't miss the spine-tingling sequel, Sanctum.
