An instant USA Today and Indie bestseller, from Hugo, Nebula, and Locus award-winning author T. Kingfisher comes an original and subversive fantasy adventure. This isn't the kind of fairy tale where the princess marries a prince; it's the one where she kills him. Marra, a shy, convent-raised, third-born daughter, is relieved not to be married off for the sake of her parents' throne. Her older sister wasn't so fortunate, though, and her royal husband is as abusive as he is powerful. From the safety of the convent, Marra wonders who will come to her sister's rescue and put a stop to this. But after years of watching their families and kingdoms pretend all is well, Marra realizes if any hero is coming, it will have to be Marra herself. If Marra can complete three impossible tasks, a witch will grant her the tools she needs. But, as is the way in stories of princes and the impossible, these tasks are only the beginning of Marra's strange and enchanting journey to save her sister and topple a throne.
