Deadly Heat by Cynthia Eden
The first time FBI Special Agent Kenton Lake sees Lora Spade, the woman is saving his butt-literally pulling him from a burning building. He takes one look at the gorgeous firefighter and falls for her, hard.
Lora isn't interested in getting involved because she lost her lover six months before in a fire-and she can't get his screams out of her mind. Lora is convinced the fire that took her boyfriend Carter was no accident.
But Kenton isn't the kind of man who walks away when he wants something-or someone. He's been sent by the Serial Services Division, an elite unit in the FBI, because they suspect that a serial arsonist is at work.
Kenton knows that Lora is just using him to avenge Carter's death. But he wants more than fleeting pleasure - he wants her. But this is not in the arsonist's plans. He's been watching Kenton and Lora.
He knows they are tracking him but they can't stop him. And they can't beat the fire. He wants to see them die.
