Deathmarch by Dana Marton

Welcome back to Broslin Creek! Can't wait to catch up with you. How about a cup of coffee at Finnegan's? You won't believe what's happening. Allie Bianchi, the town bum's daughter, just blew back into town. UP. TO. NO. GOOD. No doubt. Well, Harper Finnegan is a police detective now. She's not going to get her hooks into him so easily this time. Not when there's murder afoot! You just watch and see. On the verge of losing her business, Allie Bianchi, a historical reenactor, must return to her hometown that never accepted her family. The sooner she leaves again, the better. But when the town recluse is murdered on the night of her arrival, his prepper hoard stolen, she becomes Detective Harper Finnegan's number one suspect. In what universe is her town black sheep ex-boyfriend now a cop, arresting her for murder?
