Edge of Twilight. Wings In the Night, #7

Strong sexual contentSexy rebel Edge (aka Edgar Poe) is on a mission to find and kill Frank Stiles, the obsessed vampire-hunter who murdered his entire undead family. And the path to Stiles leads straight through the legendary half-vampire, half-mortal "child of promise" Amber Lily. Amber Lily Bryant is a legend among the undead, yet even she doesn't know the full extent of her nature or her powers.
She's one of a kind. But now, she's on a mission of her own to protect Frank Stiles from Edge's vengeance, even though he once abducted and tortured her. She must keep the vampire killer alive because he might possess the secret that could save the life of her dear friend. They are opposite sides in a deadly race against time, yet the passion between Edge and Amber is too potent to be denied. And soon, both their lives hang in the balance.
