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?
