Oh, fudge! / Nancy Coco.
(Book)

"After Allie inherited her family's McMurphy Hotel and Fudge Shop, cousin Tori moved off to California in a bitter huff, and the two haven't spoken since. So to have her cousin reappear on Mackinac Island without warning is a big surprise--but not as surprising as finding her standing over a dead woman impaled with a garden spade in the Mackinac Butterfly House. Butterflies may be free, but Tori won't be for much longer--unless the cousins can bury the hatchet and work together to catch a killer who's taken flight. Because when it comes to family, blood is thicker than fudge..." --Back cover.
