November 2nd excerpt:

Sam scanned Jacob up and down, as much of the tall teenager as he could see from his seat on the table. “But really, we’ll need to get you a change of clothes. You can’t pull off a disguise looking like that.”

Jacob’s eyebrows shot up and he could feel his face heat up. He glanced down at himself, at the rumpled hoodie he wore over worn jeans. He’d dressed for a camping trip. He definitely hadn’t planned for someone four inches tall to appraise him. At most, Bowman would have a snarky comment about the zipper on the front, because zippers had fascinated the little sprite since they first met.

Sam has a knife he can use to cut his hair. It’s perhaps not as precise as scissors, but he keeps it sharpened and it gets the job done. For the most part, he doesn’t cut his hair often, merely keeping it straight as it grows out.

Others will find sharpened scraps of metal to use if they live near humans. Those that live out in the wilderness often let their hair grow wild, or can use sharpened stones to cut it if it begins to get in their way, a problem while trying to survive.
