Zick, Elena's new neighbor, is a strange kid who's allergic to just about everything, but he alone has the power to see the invisible ghosts and monsters that live among us.

Together, Zick and Elena are out to investigate all the strange phenomena going on in Oldmill Village, including a recent uptick in missing pets, a dangerous man-eating plant, and a sinister salesman who could pose the ultimate threat to both humans and monsters alike!
