Byx is the youngest member of her dairne pack. Believed to possess remarkable abilities, her mythical doglike species has been hunted to near extinction in the war-torn kingdom of Nedarra.
After her pack is hunted down and killed, Byx fears she may be the last of her species. The Endling. So Byx sets out to find safe haven, and to see if the legends of other hidden dairnes are true.
Along the way, she meets new allies??both animals and humans alike??who each have their own motivations for joining her quest. And although they begin as strangers, they become their own kind of family??one that will ultimately uncover a secret that may threaten every creature in their world.
