The empire is named for the tiny island and city of Malaz, now a sleepy, seedy backwater port. Tonight however, a once-in-a-generation Shadow Moon brings demon hounds and darker beings. Also, a prophecy promises the return of long missing Emperor Kellanved to the contended imperial throne. This night will determine the fate of the world.

With her country's future and her own life at stake, an orphaned duchess must journey into a world of myth and there discover a power that may be her salvation—or her demise—in this enchanting new novel from the New York Times bestselling author of the Winternight Trilogy and The Warm Hands of Ghosts. Anne of Brittany was a child when her realm was invaded, her home besieged, and her royal father driven to his death. Now her treasury is empty, her land occupied by her enemies, and she is ordered, under threat of renewed war, to become queen of her conquerors and marry the King of France. This marriage means her country’s annexation. But Anne promised her father that Brittany would never be conquered. Defiantly, she betroths herself in secret to France’s greatest enemy. But in a world where courts may spy on each other by magic, there is only one way to solemnize this illicit union. Anne takes her court deep into a legendary forest, where the court diviners’ skill cannot reach. The world thinks they are only a hunting party, coursing after unicorns. But that is a lie, a trick, a feint. No one in living memory has seen a unicorn. All Anne wants is this secret wedding, which is her only hope of salvation. But when against all hope a unicorn appears and a stranger out of legend stumbles from the trees and falls at her feet, Anne is plunged into a world of enchantment where a doomed sovereign might find the power to change her own and her country’s destiny—or be lost in the shadows forever.
