Nya, a wise woman, and Yaro, the town Windsinger, try to heal the damage and halt the spread. However, something goes awry and they both slip sideways into another world. Nya emerges alone, greeted only by Yaro’s ghostly windsinging. During her dangerous search for him she must combat the will of powerful figures who wish to hold him for their own ends. But rescuing the man she loves won’t solve the bigger problem. The evil that harmed the Witterkin now threatens both worlds. To fight it, Nya will have to delve deep into her own mysterious heritage.
