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.

Elspeth needs a monster. The monster might be her. Elspeth Spindle needs more than luck to stay safe in the eerie, mist-locked kingdom of Blunder—she needs a monster. She calls him the Nightmare, an ancient, mercurial spirit trapped in her head. He protects her. He keeps her secrets. But nothing comes for free, especially magic. When Elspeth meets a mysterious highwayman on the forest road, her life takes a drastic turn. Thrust into a world of shadow and deception, she joins a dangerous quest to cure Blunder from the dark magic infecting it. And the highwayman? He just so happens to be the King’s nephew, Captain of the most dangerous men in Blunder…and guilty of high treason. Together they must gather twelve Providence Cards—the keys to the cure. But as the stakes heighten and their undeniable attraction intensifies, Elspeth is forced to face her darkest secret yet: the Nightmare is slowly taking over her mind. And she might not be able to stop him.

Nesta Archeron has always been prickly-proud, swift to anger, and slow to forgive. And ever since being forced into the Cauldron and becoming High Fae against her will, she's struggled to find a place for herself within the strange, deadly world she inhabits. Worse, she can't seem to move past the horrors of the war with Hybern and all she lost in it. The one person who ignites her temper more than any other is Cassian, the battle-scarred warrior whose position in Rhysand and Feyre's Night Court keeps him constantly in Nesta's orbit. But her temper isn't the only thing Cassian ignites. The fire between them is undeniable, and only burns hotter as they are forced into close quarters with each other. Meanwhile, the treacherous human queens who returned to the Continent during the last war have forged a dangerous new alliance, threatening the fragile peace that has settled over the realms. And the key to halting them might very well rely on Cassian and Nesta facing their haunting pasts. Against the sweeping backdrop of a world seared by war and plagued with uncertainty, Nesta and Cassian battle monsters from within and without as they search for acceptance-and healing-in each other's arms.
