Prepare to be entranced by this utterly unique and completely spellbinding dark fairy tale from the million-copy bestselling M. R. Carey, author of The Girl With All the Gifts.
"A marvelous dark fable. This novel confirms M.R. Carey's place among the best living writers in horror and fantasy."-Christopher Buehlman, author of Between Two Fires
In a kingdom forgotten by history, a legend unfolds ...

Wounded in his county's endless wars, former soldier Mag Tresti finds work in the home of a reclusive widow, Jannae Mirchella. But Jannae is more than she seems. A witch of great skill and might, she hides her powers and her deep-laid plans behind a mask of harmless respectability. 

When a dead demon falls out of the sky, the fates of the soldier and the witch are irrevocably intertwined. On the demon's body Mag finds a tinderbox-an artefact of terrifying magical power that can not only grant his every wish, but also change the fate of nations. 

This is a tale of spellcraft and devilry, of witchcraft and trickery-of the wickedness that resides within a few, the goodness that lies deep within us all, and the choices on which our lives turn.
