Her Only Hero (The Flanagans #3)2005

Penniless widow Laura McKay was determined to succeed on her own, but when an arsonist threatened her deaf daughter's safety, she was compelled to rely on firefighter Ryan Flanagan, the high school football hero who'd never noticed her as a shy underclassman.

Physically fearless and an expert at avoiding romantic commitment, Ryan had nearly become his own worst enemy. But in the flames there's only one enemy: time, which just might be running out for Laura, unless Ryan's courage...and love...can withstand the test of fire.
