House of Hollow by Krystal Sutherland

As children, the Hollow sisters—Iris, Vivi, and Grey—vanished without warning from their peaceful neighborhood. They reappeared weeks later with no memory of what happened, naked except for the flowers tangled in their hair and a half-moon scar at the base of their throats. And they’ve changed. Insatiably ravenous, their hair fades to white, their eyes turn black, and they are strikingly gorgeous, able to enchant admirers with a glance or a touch. A decade after their abduction, they agree to meet at a concert, but Grey disappears for the second time. Determined to find her, Iris and Vivi follow the cryptic trail left by their eccentric older sister, unearthing clues about Grey’s secret life and the sinister dark magic tied to their abduction. In the tradition of Grimm, House of Hollow is an immersive urban fairytale, beautiful and terrifying, as Iris and Vivi confront the dangerous truth of their past—and themselves. Sutherland’s haunting tale of three sisters’ loyalty, tainted by horrifying, otherworldly secrets, slowly builds to a disturbing and unforgettable climax.
