The island fishing village of Eastport, Maine, has plenty of salty local character. It also has a sweet side, thanks to Jacobia 'Jake' Tiptree, her best friend Ellie, and their waterfront bake shop, The Chocolate Moose. But when island life is disrupted by the occasional killer, Jake and Ellie put their chocolate treats aside to make sure justice is served. This summer, Eastport’s favorite lovebirds, kindergarten teacher Sharon Sweetwater and Coast Guard Captain Andy Devine, are getting married. The gala reception is sure to be the fête of the season, especially with a wedding-cake-sized whoopie pie courtesy of The Chocolate Moose. For Jake and Ellie, the custom-ordered confection will finally reel in some much-needed profits. But the celebratory air, and sweet smell of success, are ruined by foul murder. When Sharon’s bitter ex-boyfriend Toby is poisoned with an arsenic-laced milkshake, Andy is jailed as the prime suspect and the wedding is cancelled, whoopie pie and all. Then Sharon makes a shocking confession-one that sounds like a fishy attempt to get Andy off the hook. Now both the bride and groom are behind bars. And with the fate of The Chocolate Moose at stake, it’s up to Jake and Ellie to catch a poisonous predator before someone else sips their last dessert.
