The Witches Pumpkin

Joey and Dianna are left stranded on a remote island after their yacht sinks into the Pacific, and one of their best friends is found dead on the opposite side of the island. How could he have gotten all the way over there when the yacht had sunk on the north side? He definitely didn't drown, but who would have done that to Jeremy?

"Why would somebody do this to Jeremy? What had he done that would spark such a gruesome thing? An even bigger question, who would it have been?"

"Dianna and I stood at the end of the shoreline gazing down at our once conscious friend. His face exposed deep cut marks across both eyes. Each of them had long traces of blackened blood trickling down both sides of his head. His fingers seemed to have been crushed flat, almost as if they were nothing but blobs of tissue. His body gave off a senseless excitement to that one might begin to consider their own death. His eyes had been stilly eyeing the birch tree overhead of himself, but his spirit appeared to wander someplace different."
