From the Sunday Times bestselling author of Starling House, Alix E. Harrow, comes a moving and genre-defying adventure through time – as a reluctant lady knight and a not-so-heroic-historian will fight through time and space to rewrite their tragic fates . . . and finally reveal the truths hidden beneath the greatest legend ever told. It begins where it ends: beneath the yew tree – a girl not yet a knight, and a boy without a story. It is where she pulls a sword from the heartwood and becomes a legend. And it is where, more than a thousand years later, he will find her – and lose her – and find her – and lose her again. It is where a new story will be written – but whose will it be?

This is the way the world ends. Again. Three terrible things happen in a single day. Essun, a woman living an ordinary life in a small town, comes home to find that her husband has brutally murdered their son and kidnapped their daughter. Meanwhile, mighty Sanze -- the world-spanning empire whose innovations have been civilization's bedrock for a thousand years -- collapses as most of its citizens are murdered to serve a madman's vengeance. And worst of all, across the heart of the vast continent known as the Stillness, a great red rift has been torn into the heart of the earth, spewing ash enough to darken the sky for years. Or centuries. Now Essun must pursue the wreckage of her family through a deadly, dying land. Without sunlight, clean water, or arable land, and with limited stockpiles of supplies, there will be war all across the Stillness: a battle royale of nations not for power or territory, but simply for the basic resources necessary to get through the long dark night. Essun does not care if the world falls apart around her. She'll break it herself, if she must, to save her daughter.
