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?

In the canton of Yarrowdale, at the very edge of the Empire's reach, an impossible crime has occurred. A Treasury officer has disappeared into thin air-somehow abducted from his quarters while the door and windows remained locked from the inside, in a building whose entrances and exits are all under constant guard. To solve the case, the Empire calls on its most brilliant and mercurial investigator, the great Ana Dolabra. At her side, as always, is her bemused assistant Dinios Kol. Before long, Ana's discovered that they're not investigating a disappearance, but a murder-and that the killing was just the first chess move by a thief who seems to be able to pass through warded doors like a ghost, and who can predict every one of Ana's moves as though they can see the future. Worse still, the killer seems to be targeting the high-security compound known as the Shroud. Here, the Empire's most brilliant minds dissect fallen Titans to harness the volatile magic found in their blood. Should it fall, the destruction will be terrible indeed--and the Empire itself will grind to a halt, robbed of the magic that allows its wheels of power to turn. Din has seen Ana solve impossible cases before. But this time, with the stakes higher than ever and Ana seemingly a step behind their adversary at every turn, he fears that his brilliant superior has met an enemy she can't defeat.

An Ana and Din Mystery Brilliant detective Ana Dolabra must prove a man's innocence to stop a civil war in the third book of the series that began with The Tainted Cup, named an Edgar, Hugo, and World Fantasy Award Finalist and one of the best books of the year (New York Times Book Review, NPR, Elle)—from the bestselling author of The Founders Trilogy. In the canton of Sapirdad, two of the Empire’s most powerful families are moments away from going to war with each other, their hundreds of retainers gathered with swords drawn. If blood is spilt, the whole of the empire may be plunged into starvation and chaos. To de-escalate matters, someone must do the impossible: prove that one family’s eldest son is innocent of a gruesome and unforgivable murder, despite the incontrovertible evidence against him. It is with this undertaking that the great detective Ana Dolabra is tasked, her assistant Din at her side—and the two find themselves racing with great speed and little dignity to the scene. As ever, the impossible proves little obstacle for the deadly combination of Ana’s intellect and Din’s keen eye, and mere hours after riding into the dusty town, Ana glimpses the greater pattern behind the crime. A deeper, subtler web of death is being woven in plain sight, by a mastermind with an ancient magical technology at his disposal. But even Ana's uncanny insight is of little use when each new suspect she uncovers ends up dead--with each new killing calculated to bring tensions between the two rival clans past the boiling point. And as Din pursues their adversary through the canton's wild ranges, sprawling ranches, and reeking slaughterhouses, he finds his loyalties divided in unexpected ways.
