The vile witch Hradian sets events in motion to free her master, the wizard Orbane, who's been trapped in the Castle of Shadows. But her scheme results in unforeseen consequences-threatening not only the world of Faery but that of mortals as well.

Rising to the challenge, the heroes and heroines of Winterwood, Summerwood, Springwood, and Autumnwood join forces to rally humans and Fey alike to a cause that may be lost before it begins.
