Two opponents must confront the cause of their obsessive fury in the latest Novel of the Elder Races...
As a harpy, Sentinel Aryal is accustomed to dealing with hate, but Sentinel Quentin Caeravorn manages to inspire in her a burning ire unlike anything she's ever known. Aryal believes the new Sentinel to be a criminal, and vows to take him out as soon as the opportunity arises. But the harpy's incessant wrath has pushed Quentin to the limit, and forces him to make a deadly vow of his own.

To put an end to the conflict, Dragos, Lord of the Wyr, sends them on a reconnaissance mission to the Elven land of Numenlaur. Forced to work together, Aryal and Quentin's mutual antagonism escalates. Each fight draws forth more passion—culminating in an explosively sexual confrontation. But when their quest reveals real danger, Aryal and Quentin must resolve their differences in ways beyond the physical, before the entire Wyr is threatened.
