The tenth installment in a charming cozy mystery series set on an island off the New England coast and featuring the cat cafe owner Maddie and her cat JJ.

Trouble is brewing on Daybreak Island...

Summer is in full swing on Daybreak Island, and JJ's House of Purrs--and the new mobile cat café--have Maddie James running nonstop with on-site cat parties.

When her mom's old best friend, back on the island for the first time since her aunt Delia vanished decades ago, asks Maddie to plan a birthday party for her granddaughter, Maddie happily agrees.

But when Maddie and her mom arrive at Delia's old house, it's empty--except for a white-and-gray cat that leads Maddie to a hidden room, where they find her mom's friend dead.

Soon Maddie learns the cat might be tied to a ghostly island legend. And as she digs deeper, she realizes she's unraveling two disappearances, forty years apart--while someone is desperate to keep the truth buried.
