Trail of Lightning

Trail of Lightning by Rebecca Roanhorse is set in the near future on the land of the Dinétah (the Navajo reservation).  It takes place after cataclysmic global warming has drowned most of the world.  There has been a (literal) rebirth of the gods and heroes of myth in the aftermath of this cataclysm.  Maggie Hoskie, our heroine, is a monster slayer and in this volume she is sent on an adventure that tests origins and skills. 

This is an exciting story that highlights the myths & legends of the Navajo people in the context of post-apocalyptic fantasy.  Recommended for those who like a good all-out fight with gods and demons.
