Rose White opened the Heaven and Earth Bakery to cater to Toronto's underground population of supernatural Others, and business is good. It is Midsummer's Eve, and as usual she has a catering contract for the Sidhe ball. Travelling with her to the festivities-with strict instructions not to eat the food-are Nick, her werewolf delivery boy, Cristina, her vampire assistant baker, and John, their entirely human case worker from the Office of Other Affairs. None of them is remotely prepared for what awaits them.
