The threat of war between Witches and Vampires means England may no longer be safe for a young Witch. Hence, Miss Violet Popplewell is sent abroad under the watchful eye of her great-aunt Vera. Without so much as a bon voyage party, Violet finds herself a visitor to the city-state of X, a mysterious place where magic is used openly and Witches and Vampires live together in harmony. Or at least, they try to get along. Violet's aunt is shocked to discover that there are Vampires staying at their pensione and alarmed to note that one of the undead is a rather handsome young man. An outburst of hostilities in X thrusts Violet into the young Vampire's arms. And, much to her dismay, she realizes she may have accidentally bewitched him with a love charm. Are the emotions that the Vampire feels true passion or just a slip of the wand?
