Mercy Thompson meets Vikings in this multi-cultural urban fantasy series.   The children of Fenrir are rising whether werewolf seeker Sonya Michaelson likes it or not. As if being the seeker of werewolves tangoing with madness wasn’t enough on her plate, a coyote shifter on the run shows up on her doorstep needing help because Navajo women are going missing—skinwalkers to be precise.   What’s worse, someone is turning them into coyote shifters, which is stripping them of their skinwalker powers.
