Chapter 8

Do you mean in chapter 8? Brian wakes in the middle of the night to a strange sound and a rotting smell. Something is slithering in his shelter. He blindly throws his hatchet, and it hits against the rock in a shower of sparks. When he does this, he feels a horrible, splitting pain in his leg, as if needles had been driven into it. He spots a dark form slithering out the door, and then feels his leg: there are quills stuck in it, and his attacker had apparently been a porcupine.
