A new T. Kingfisher book is always a delight, and this is no exception. Mona is a wizard. But her only talent lies in dough – the bread kind – and her ability to make a carnivorous sourdough starter that once ate a rat. When she opens up the bakery one morning, and finds a corpse on the floor, Inquisitor Oberon promptly accuses her of murder. Things go from bad to worse. Someone is murdering wizards, even the small and insignificant kind. Mona finds herself on the endangered species list and then – even more scarily, finds she's the only wizard in town when a vicious invading army arrives. With a fourteen year old heroine this book hovers between upper-end middle grade, YA, or it can equally enjoyed by adults who like quality literature.
