A mysterious presence stalks the hallways of the Sky-King's palace, stealing dreams and condemning the king's dancers to a living death. The task of unraveling this mystery falls to young Aesva, the last living bearer of the Gift. But she is young; inexperienced; and the woman most able to assist her has already died.

Only Aesva can see the heartfires that flicker in the souls of the king's dancers. Only she knows that the heartfires are vanishing. Desperate to protect her loved ones, aided by a cadre of timid, silver-furred tamarins, Aesva must find a way to stop the unseen soul-thief that walks within the halls of the Sky-Palace.
