The trichinosis worm is one of nature's most revolting parasites. Certain types of this tiny worm alter a host's DNA by injecting a virus which mutates the reproductive system. This forces the host to bear the worm's young. Typically these worms are never longer than a few millimeters. But guess what? Now there's a subspecies that's thirty feet long...When Nora and her team arrive at the island, she expects a routine zoological excursion...but it doesn't take her long to realize they're not alone. Are her lurid sexual dreams making her paranoid...or is she being watched? The dead bodies they find are bad enough, but then her own team members begin to disappear, and when they return, they've...changed. Indeed, there are other people on the island...along with something else far worse.
