Keira is convinced her guardian, Ezekiel, knows more than he shared about her biological parents, and she will do everything she can to find out who they were. She secretly meets the powerful witch Awan at a nightclub and is promised the answers she seeks on one condition: she retrieves the legendary Book of Enchantresses. Keira, along with Uriel, Samyaza, Jonah, and her Nephilim friends, must travel to another realm in Gotjawal Forest on Jeju Island to recover the spell book. But nothing is free, and actions have consequences. When Keira's team returns to their world, vampires attack a demon stronghold. No one knows who to blame, but the fragile peace has been rocked. And it's about to get worse--Lucifer has escaped Hell.
