Within the Flames by Marjorie M Liu

Within the Flames:
Joining the Dirk and Steele Agency turned Eddie's life around. A pyrokinetic and former car thief, he cannot refuse an assignment to cross the continent in order to rescue an extraordinary woman in peril...even though he fears losing control of the destructive power of flame at his fingertips.

The last of her shape-shifting kind, Lyssa hides in the abandoned tunnels beneath Manhattan, seeking refuge from those who murdered her family a decade ago and would now destroy her as well. Like Eddie, fire is her weapon, her destiny... and her curse. Yet she wants nothing to do with this mesmerizing stranger who seeks her trust while inflaming her passion. For beneath Lyssa's extraordinary beauty are dangerous secrets... and even darker, nearly irresistible urges. But she has won the heart of a fearless protector... and all the demons in the world will not make him back down.

Marjorie M Liu has one of the most creative imaginations I have ever encountered. Her books are never disappointing and I have been waiting for Eddie's story ever since I first met him in Tiger Eye. Ever since Eddie lost control of his fire he's been alone, and finally there is a woman who can withstand his fire and add to it with her own. It's been incredible to watch him develop over the course of the Dirk & Steele series, and I know fans are going to love this newest addition. Eddie is a hero, even when he doesn't want to believe it, he believes in doing the right thing no matter what the cost. Lyssa is a powerful woman who is afraid to trust herself, she protects those around her even while trying to avoid forming any kind of affection. I loved seeing a few past characters of the series woven into the story; and in fact, we learn a little something new about the relationship between Eddie and Roland (the powerful leader behind the Dirk & Steele detective agency). Marjorie's characters are deeper than they first appear, and some of the secrets they hide could damage more than just relationships. But with trust and love Eddie and Lyssa fight their demons in order to save others from a powerful evil the seeks not only to destroy, but take their power for her own.
