Trail Of Lightning

"An apocalyptic flood has devastated most of North America – all but the Diné nation, which grew magical walls of abalone, turquoise, white shell and jet to protect itself. But in addition to the destruction, the flood has ushered in the Sixth Age, opening up the human world to spirits and monsters again. Maggie Hoskie is a monster-hunter who keeps people safe for pay – but when she defeats a monster that seems to have been crafted by magical means to malicious ends, she must team up with a silver-tongued man named Kai to find out who or what is behind it. Fast-paced and innovative, Trail of Lightning reads like an indigenous answer to questions Supernatural never thought to ask."
