Blackwood (Blackwood #1)

When four teenagers with haunted pasts enroll in Blackwood College - a school that trains students in the occult - their desire to enhance their supernatural abilities and bond with others is hampered by an undead dean’s curse, ghosts in their dorm, a mischievous two-headed mummy-chimp, a plague of mutant insects, and the discovery of an ancient evil that forces our heroes to undergo a crash course in the occult for the sake of the world.
