I grabbed Shaman, Healer, Heretic from the KDP free list.

Description from Goodreads:
Even for a techno-shaman, a kachina in the bedroom isn’t exactly part of the drill. When Olivia Lawson wakes to find one towering over her, she panics. A Hopi god visiting the real world isn’t just wrong-it’s impossible.

Or is it?

Soon Olivia learns that the kachina is the least of her worries. As she struggles to save her clients, clashes with other shamans, and fends off the attacks of real-world vigilantes, Olivia finds herself in the destructive path of a malevolent ancient force intent on leaving the spiritual realm to conquer this one.

Left with few options, Olivia is forced to defy centuries of shaman prohibitions. As she and her allies risk everything in their bid for survival, Olivia ultimately learns that the rules are there for a reason and that breaking them has a terrible cost.

Review:
Shaman, Healer, Heretic starts with a spark and retains it throughout. It is fast-paced and easy to get wrapped up in. Techno-shamans are an interesting addition to the paranormal genre and I really appreciated the inclusion of some lesser used cultural and religious references, Hopi and Sumerian for example.

I found some of it a little predictable, but this was more than compensated for by the engaging characters. While Green left some aspects of Livvy’s character shrouded in mystery she was a lot of fun. The other shamans each had a distinct character, adding variety to the book. On the downside, since the book is so fast-paced there wasn’t a lot of opportunity to become as invested in the characters as one did in the conclusion of the challenges presented. You liked them, but didn’t have a deep understanding of their personality. Mostly I would just callShaman, Healer, Heretic a fun, quick read.
