Celia Small has spent years planning her engagement party, from the food she'll serve to the dress she'll wear. When she finally met her fiance, it was less a romantic event than a satisfying check mark next to the last item on a long list of tasks. Now Celia's big night has arrived, and nothing can stop her from fulfilling a lifetime's worth of dreams. Nothing, that is, except her hated housemates, each planning a party for this same evening. Suddenly careening between future in-laws, radical feminists, and an Alice in Wonderland costume party, Celia veers off the path to married bliss, and along a path of suspicious raspberry tarts that lead her into very strange places.
