After Lindsey Bakeswell catches her celebrity chef fiancé sizzling in the arms of another woman, Lindsey leaves big city Wall Street for small town Beacon Harbor, Michigan, to pursue her own passion as a pastry baker--and gets mixed up in someone's sweet taste of revenge . . . More interested in kneading dough than adding it up, Lindsey's breakup inspired her to set up the shop she always wanted in a place that always made her happy. She'd spent many childhood summers near this beach community and converting the old run-down lighthouse into a bakery café and home offers a perfect fresh start for Lindsey. But not everyone in town has a sweet tooth. The preservation society won't have the lighthouse's history sugar coated by lattes and cakes--and a protest group crashes Lindsey's Memorial Day opening. Then her ex-fiancé Jeffrey Plank and his girlfriend Mia Wong arrive to trash the place. In the ensuing chaos Mia chokes on a donut and dies. An autopsy reveals cyanide in Mia's bloodstream and Lindsey is the police's prime suspect. To clear her name, she's going to need to combine ingredients found in the town's checkered past to uncover the identity of a desperate killer . . .
