Witch's Bell Book Four — Odette C. Bell

Things have changed for Ebony, but they're about to change more. Only months after defeating the Relator, she is plunged into a new conflict. This time the big forces are getting involved too; Nature itself has singled her out for an impossible task.

Soon Ebony is knee deep in a mysterious disappearance, cults, and demons. Lots of demons. But if she can't push through it all, she'll run out of time. Literally.
