Lint and Hgh

Clan Chief Ghun comes back from a hunt with a rare, new beast: two legged Hgh. At first, the villagers are wary of Hgh, but he is accepted and given the position of teacher when he shows the villagers how to make a new weapon: the arrow. Lint is the only person still suspicious. Why is Hgh making so many arrows? Why does Hgh go for a walk on the rocky plateau every day? And why is Hgh turning everyone against Lint, even his own Ma. Hgh, Lint decides, has to be stopped!
