Led by Meoran, the Named herd horses and deer for food. They keep order and peace, fending off predatory raiders - the UnNamed - from all sides.

But, her tribe needs her. Can she return Will the Named survive constant attacks without the Red Tongue Will the power of the Red Tongue change the clan forever
