Whispers of Spitfire: Sky Wolf

From the back cover:

In the midst of a new ice age, brave shamans hunt gods born of black glass and steel. The blood of these gods is sacred, and the shamans of each tribe are marked with the sacred blood in ways that give them strange, supernatural abilities.

This is the second book in the story of a young shaman of the Eikus Tribe. Taking a winter to learn the songs and stories of the Sky Wolf Mother of Vitsena tribe, Sun-Among-Cedars finds a place in the pack, but only by following a rough path of self-discovery.
