Two sisters. One brutal murder. A quest for vengeance that will unleash Hell itself . . . A new series from the #1 New York Times bestselling author of Stalking Jack the Ripper. Emilia and her twin sister Vittoria are streghe - witches who live secretly among humans, avoiding notice and persecution. One night, Vittoria misses dinner service at the family's renowned Sicilian restaurant. Emilia soon finds the body of her beloved twin . . . desecrated beyond belief. Devastated, Emilia sets out to find her sister's killer and to seek vengeance at any cost-even if it means using dark magic that's been long forbidden. Then Emilia meets Wrath, one of the Wicked-princes of Hell she has been warned against in tales since she was a child. Wrath claims to be on Emilia's side, tasked by his master with solving the series of women's murders on the island. But when it comes to the Wicked, nothing is as it seems . . .

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.
