This isn't the kind of fairytale where the princess marries a prince.

It's the one where she kills him.

Marra never wanted to be a hero.

As the shy, convent-raised, third-born daughter, she escaped the traditional fate of princesses, to be married away for the sake of an uncaring throne. But her sister wasn’t so fortunate — and after years of silence, Marra is done watching her suffer at the hands of a powerful and abusive prince.

Seeking help for her rescue mission, Marra is offered the tools she needs, but only if she can complete three seemingly impossible tasks:
— build a dog of bones
— sew a cloak of nettles
— capture moonlight in a jar

But, as is the way in tales of princes and witches, doing the impossible is only the beginning.

Hero or not — now joined by a disgraced ex-knight, a reluctant fairy godmother, an enigmatic gravewitch and her fowl familiar — Marra might finally have the courage to save her sister, and topple a throne.
