The Brain-Case Soiree (Infected Voices #4) by Robert Essig

If the walls could talk, they'd tell you to stay the fuck away from the abandoned asylum. But they don't say a word as you walk in. It'll be a fun time. We can explore and take pictures. Problem is, someone lives there, and they don't take kindly to strangers. If you hear the wheeeeeee of a power drill . . . RUN LIKE HELL!
