The Bad Boy of Butterfly Harbor by Anna J. Stewart

Can people truly change?

Two things keep Holly Campbell grounded: her precocious son and preserving her forty-year-old family diner in the face of expansion and change. She doesn't need a blast from the past like Luke Saxon, who's back in Butterfly Harbor after more than a decade away. The hard-luck kid who nearly destroyed her family, leaving her to pick up the pieces, is taking over as sheriff. She can't trust him, even if Luke's ideas for the town's upcoming anniversary seem to show he's trying to give back to their community. Has Butterfly Harbor found its unlikely savior? And has the widowed single mother finally found a man she can believe in, rely on...and love?
