The Witch’s Progress Omnibus [EPUB ebook] 

All four books of The Witch’s Progress, collected into a single omnibus!

Tara seems like a perfectly normal person. She works two jobs to cover the rent, her boss takes advantage of her good nature, and she constantly studies so she can progress and pass into the next circle of witchcraft.

But a supernatural being takes interest in her, wanting to trap her soul.

A twisted look into the heart of Portland, the secrets behind its bridges, and the magical battles that happen even among friends.

This omnibus contains the following novels:

Circle of Air
Circle of Fire
