When Lucy Winters inherits her great-aunt's fudge shop on charming Mackinac Island, she expects a quiet summer of candy-making and tourist watching. What she doesn't expect is a double murder, a judgmental orange cat named Felix, and two very different men vying for her attention.

Fresh from a corporate marketing job and a messy breakup in Chicago, Lucy is determined to prove she can run Mabel's Marvelous Fudge—even if she can barely tell a candy thermometer from a tire gauge. With help from her quirky teenage employees and the island's self-appointed Fudgeamentals committee (a group of elderly confectionery enthusiasts with strong opinions about everything), Lucy slowly finds her footing in her sweet new life.

But when the island's wealthy power couple turns up dead under suspicious circumstances, Lucy discovers that paradise has a dark side. Between dodging the Fudgeamentals' amateur detective theories, navigating romantic tension with rugged bike shop owner Jake Miller and polished lawyer Ethan Hayes, and earning the approval of Felix—the island's most discerning feline critic—Lucy has her hands full.

When someone vandalizes her shop and leaves threatening messages, Lucy realizes the killer isn't finished. With Felix as her unlikely sidekick and the Fudgeamentals as her enthusiastic backup, she'll need all her marketing skills and newfound island connections to solve the mystery before she becomes the next victim.

A deliciously entertaining cozy mystery filled with small-town charm, romantic entanglements, and one very opinionated cat who might just be the best detective on the island.
