As grade twelve exams finish, Dara anticipates a summer working in the family market garden and hanging out with her friend Korina. But when her friend heads out to jog on the Georgian Trail outside Thornbury, a strange shadow attacks her. Out at the mound south of the town on the night of the solstice, when a stranger William joins them, a giant shadow-creatures comes after them. From thing Dara’s father does, they realize that the dangerous creatures are somehow connected to his search for a revolutionary renewable power source.

With his help, Dara and her friends fight the poisonous by-products he released into Faerie, working to rescue him before he succumbs to the power he unleashed.
