Falling Ash by Beck Daniels

A curvy young woman on the run from her old life, Zoe will do anything to keep her past in the past. But when she ends up stranded on the side of the road after her car spins out on a stormy night, she finds herself in a heap of trouble.
Ash leads his men on one of his famous “midnight runs.” Rain or shine, this elite wildland firefighting crew gets their miles in. But, when they happen upon the heartstopper who’s not such a damsel-in-distress, he struggles to maintain his professionalism.
