Bone ​Criers have a sacred duty. They alone can keep the dead from preying on the living. But their power to ferry the spirits of the dead into goddess Elara’s Night Heavens or Tyrus’s Underworld comes from sacrifice. The gods demand a promise of dedication. And that promise comes at the cost of the Bone Criers’ one true love. Ailesse has been prepared since birth to become the matriarch of the Bone Criers, a mysterious famille of women who use strengths drawn from animal bones to ferry dead souls. But first she must complete her rite of passage and kill the boy she’s also destined to love. Bastien’s father was slain by a Bone Crier and he’s been seeking revenge ever since. Yet when he finally captures one, his vengeance will have to wait. Ailesse’s ritual has begun and now their fates are entwined—in life and in death. Sabine has never had the stomach for the Bone Criers’ work. But when her best friend Ailesse is taken captive, Sabine will do whatever it takes to save her, even if it means defying their traditions—and their matriarch—to break the bond between Ailesse and Bastien. Before they all die.

Love is a matter of life and death. Bone Criers have been ferrying the dead into the afterlife for centuries, a dangerous duty only possible with the powers they gain from sacrificing their amourés the men destined to love them and die. But Bone Criers Ailesse and Sabine—along with Ailesse’s love, Bastien—are working to chart their own course and rewrite the rules of the afterlife. If they don’t break the soul between Ailesse and her amouré, she could die—just as Bastien’s father did. Sabine struggles to maintain her authority as matrone of her famille—the role always destined for her sister—even as she fights to control the violent jackal power within her. Bastien is faced with a new dilemma as the spirits of the Underworld threaten the souls of his friends—and his father. Ailesse attempts to resist her mother’s siren song as she’s drawn into her own version of the Underworld. How will she save her friends once she’s cut off from their world? This pulse-pounding follow-up to Bone Crier’s Moon is a story of love, sisterhood, and determination as three friends find the courage and power to shatter the boundary between the living and the dead.
