After a long, snowy winter on Daybreak Island, Maddie and her cat cafe crew are finally ready to embrace the spring, though life is anything but calm. With Val and Ethan's wedding taking center stage, Maddie finds herself juggling wedding plans alongside a new and unexpected venture--a generous donation has made her the co-owner of a traveling cat cafe truck. To kick off the new chapter, she seizes the chance to take the truck on its inaugural trip to a cat literary festival in Provincetown, accompanied by her family and some of the shelter crew. The festival is organized by the renowned cat-romance author Jasmine Prescott, who also runs a beloved cat rescue foundation on Cape Cod. But when Jasmine's longtime friend and fellow author Vivi St. Clair arrives with a boatload full of drama--everything from a dangerous ex-husband to an unwanted Netflix crew--tensions run high. At first, it seems like just another dose of celebrity chaos--until Vivi is found murdered. As new evidence ties Maddie and her cat cafe into the investigation, Maddie must dig deeper into the tangled web of secrets, rivalries, and feline-friendly drama to uncover the truth. The question is: what's the connection between the cat cafe and Vivi's untimely death?
