"Rui has her life back together--or so it seems. Hailed as a hero, she's finally on her way to becoming an important member of the Exorcist Guild. But she knows the Hybrid Revenants are still out there, and they're planning something big. Something evil. Zizi is trapped in the underworld. As his mortal body deteriorates, he realizes he can access the Fourth King's memories, which may be the key to keeping the mortal realm safe. To save the girl he loves, he must defy fate--and escape Hell. Yiran watches from the shadows, magicless once more. When he discovers a dark family secret that changes everything he thought he knew, his hunger for power tempts him toward a possible betrayal. And he must decide what he truly stands for--before it's too late. As the consequences of the past wreak havoc on the present, three lives bound by the threads of fate must weave a new destiny for themselves--and the realms.
