Rescued Faith by Lisa Phillips

When private detective Penny Mitchell’s latest case takes her right back to the last place on earth she wants to go, she must make a choice—continue running from her past, leaving Last Chance County for good, or stay and ensure that her sister and her kids are safe. Even if that means running into her ex.
Rescue firefighter and notorious playboy Bryce Crawford is supposed to be a different guy now that he’s come to faith, but he isn’t exactly sure how to do that—especially when the woman who broke his heart comes back to town. As if seeing Penny isn’t dangerous enough, they have to work together on a new task force to find the criminals responsible for the recent string of explosions and epidemic of dangerous new weapons on the streets.
Together, Penny and Bryce must set aside their past and race against time to uncover the criminals’ end game…and stop them before it’s too late.
