Fourteen-year-old Mona isn't like the wizards charged with defending the city. She can't control lightning or speak to water. Her familiar is a sourdough starter and her magic only works on bread. She has a comfortable life in her aunt's bakery making gingerbread men dance. But Mona's life is turned upside down when she finds a dead body on the bakery floor. An assassin is stalking the streets of Mona's city, preying on magic folk, and it appears that Mona is his next target.
