Tempting Fate by Sara Whitney

Second chances can be twice as hot

Faith Fox grew up rich, but she burned that bridge—and her trust fund along with it—after her parents drove away the only boy she ever loved.
Leo Morales grew up poor, and although he carved out a fulfilling career for himself, he never forgot the humiliation he endured at the hands of Faith Fox’s family.
Then Leo’s offered a job in his hometown, and he finds himself in an unexpected position: he’s now the one with the money Faith needs to keep her non-profit afloat.
The pair reluctantly agree to work together, but their unresolved issues (and their unstoppable lust) keep boiling over—and that’s before they get stuck in the woods with only one tent.
