In the luscious, dark sequel to One Dark Window, Elspeth must face the consequences of what she's wrought - perfect for readers of Hannah Whitten's For the Wolf and Alexis Henderson's The Year of the Witching. Elspeth and Ravyn have gathered most of the twelve Providence Cards, but the last, and most important one remains to be found: The Twin Alders. If they are going to find it before the Solstice and cure the kingdom of the dark magic infecting it, they will need to journey beyond the dangerous mist-cloaked forest that surrounds their kingdom. And the only one who can lead them there is the monster that shares Elspeth's head. The Nightmare. And he's not eager to share any longer.

Wei Wuxian was once one of the most powerful men of his generation, a talented and clever young cultivator who harnessed martial arts and spirituality into powerful abilities. But when the horrors of war led him to seek more power through demonic cultivation, the world's respect for his abilities turned to fear, and his death was celebrated throughout the land. Years later, he awakens in the body of an aggrieved young man who sacrifices his soul so that Wei Wuxian can exact revenge on his behalf. Though granted a second life, Wei Wuxian is not free from his first, nor the mysteries that appear before him now. Yet this time, he'll face it all with the righteous and esteemed Lan Wangji at his side, another powerful cultivator whose unwavering dedication and shared memories of their past will help shine a light on the dark truths that surround them.
