Janner, Tink, and Leeli Igiby, the Lost Jewels of Anniera, are hiding from Gnag the Nameless in the Green Hollows, one of the few places in the land of Aerwiar not overrun by the Fangs of Dang.

To the suspicious folk of the Green Hollows, he looks like a monster.
But Janner knows better. His brother isn't as scary as he looks. He's perfectly harmless. Isn't he?
