An isolated compound. A so-called family. A collision course with unthinkable violence. When Winona rents a room at the eccentric Mirror House, she hopes to make new friends. What she gets instead is a “family” led by the charismatic psychologist Simon Spellmeyer. But if she wants to stay at Mirror House, Winona must join in following Simon’s strange protocols for self-improvement. Warning bells chime inside her, but she ignores them. Yes, his methods are disturbing, but the results are undeniable. Soon, Simon’s vision for their future spirals in a darker direction. The group relocates, expands, and Winona’s once-close bond with her housemates grows fractured by mistrust until she’s trapped among people she hardly recognizes. Including herself. Can Winona wake up to the true cost of Simon’s vision in time to get out alive? Or will the utopian dream turn into a tragic nightmare?

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.
