agining of the Persephone myth for fans of Lore Olympus and Melissa Albert, two former best friends--split apart by betrayal--find themselves reunited in the Underworld. But will either one make it out, or will the darkness that's growing in each of them consume them whole?

For all of Corey's life, it's been Bree and Corey, Corey and Bree. Best friends, the girls are inseparable--until a devastating betrayal leaves Corey shattered and alone. Corey is sure nothing could hurt more, until Bree suddenly dies. Now Corey is heartbroken and furious. How can she mourn her one-time friend when she is still so angry at her?

Yet Corey and Bree's tale is far from finished. When Corey accidentally catches a glimpse of Bree's spirit passing into the afterlife, she finds herself face to face with a god pulled from the darkest myths of her girlhood: Hades, lord of the dead.

Turns out, the legends are real. But Hades is different from what Corey imagined--and so are the Furies, terrifying and beautiful creatures who encourage Corey to embrace her rage. The more Corey discovers about the Underworld, the more her own power stirs. But can she resist the lure of the darkness within?
