Summer guests are eager to sink their teeth into the tantalizing desserts Jacobia "Jake" Tiptree and Ellie White serve at their bakeshop in the island village of Eastport, Maine. But attracting the wrong kind of attention can be deadly . . .

With the August heat strong enough to melt solid chocolate into syrup, Jake and Ellie crave a break from the bakery ovens, despite tourist season promising a sweet payday. But they never envisioned spending the last weeks of summer drifting around Passamaquoddy Bay searching for pirate's treasure-and a dead body.

Sally Coates believes her husband was murdered off the coast, and begs Ellie, a trusted childhood friend, to locate his remains. It's unusual that a skilled fisherman would vanish along with the gold doubloon he inherited from his grandfather. And Sally isn't the only one coveting the valuable heirloom for her own.

As Jake and Ellie's island-hop for answers, they find themselves caught between hungry sharks and hungrier suspects. Can the duo tempt fate and dodge danger before there's blood in the water-or are they destined to fall into the jaws of a killer's trap?
