Against The Fire by Kat Martin

Gabriel can't be sure just who's setting the fires in his new real–estate development. When two fires hit back–to–back, he knows it's personal, but any number of competitors or ex–employees could be the arsonist. The police suspect Angel Ramirez, a local teen who's been in trouble before. But Mattie Baker –– a volunteer at the family abuse centre –– just can't believe the kid she's been working with would revert back to his delinquent ways.

Determined to convince Gabe that she's right, Mattie must get close to him and find out who's putting their neighbourhood in jeopardy. As the arsonist's flames continue to burn, they find a heat developing between them. It might just turn into a full–fledged fireif they can survive long enough.
