Treason of Hawks,

"Rhett Walker is looking for peace, the memories of all he's lost haunting his dreams. And now the Shadow tugs him West, back to where his journey began. With the lawless Rangers on his heels and monster attacks surging, Rhett is surrounded on all sides. This time it's not all about horses and land. This time, it feels personal. Because the newest monster on the horizon just may be wearing the face of someone from Rhett's past. To save the Durango territory, Rhett must accept the Shadow's call and fulfill his destiny."--
