For Killian, always being on the run from something was like a young lion who knew how to roar- it was an instinct, a habit. He never knew what he was running from, he just grew up learning to run. He didn't know that he was being hunted. Now Killian and his sister, Ryder, must find a girl named Tex, the daughter of the Hunters' founder. Can they save the world and humanity with the help of the enemy's offspring?
