Book 1 in the Night Seekers series.

Jonah Grey, driven by a lust for the blood of the legendary Chupacabra that murdered the woman who was to be his mate, jumps at the offer to leave the FBI and join Night Seekers, who are dedicated to hunting and killing the devil beast.

Then Jonah encounters a woman with whom he shares explosive chemistry that neither can deny—and sex that brings a level of pleasure neither has ever known. Soon he's dividing his time and indulging in erotic bouts of orgasmic lust with Dakota.

But the devil beast must still be dealt with, and the wolf in Jonah won't rest until the Chupacabra is dead.
