Supernatural creatures create chaos across an unforgiving western landscape in the third book of a propulsive and cinematic fantasy adventure series that began with Wake of Vultures.
"I don´t care what else you´ve seen in the bookstore today. Buy this book because it´s the thrilling, delightfully written, and important one you´ve always wanted to read."―Kevin Hearne, New York Times bestselling author on Wake of Vultures
The Ranger known as Rhett has shut down a terrible enterprise running on the blood of magical folk but failed to catch the dark alchemist behind it. And now the Shadow refuses to let him rest.
Rhett must make the ultimate transformation if he has any hope of stopping the alchemist or fulfilling his destiny; he must become the leader of a new Rangers outpost.
But to save his friends, and the lives of countless others, Rhett will first have to lead the Rangers on a mission more dangerous than anything they´ve ever faced.
