For a small New England town, Shadow Grove has an uncanny ability to attract the worst kind of trouble. Not that the residents are too concerned about the various horrors living among them.
As the leaves change color and the weather grows colder, a foul presence is making itself known by leaving peculiar gifts for the students of Ridge Crest High. At first, the presents seem harmless--and a rash of accidents seem coincidental--but when seniors Rachel Cleary and her Scottish cousin, Dougal Mackay, find a boneless body in the boiler room, things take an ominous turn.
Something vicious is on the loose in Shadow Grove, but with Orion Nebulius gone, Rachel has little hope of anyone getting out alive.
