Dragon's Bait Reprint edition

Fifteen-year-old Alys is not a witch. But that doesn't matter--the villagers think she is and have staked her out on a hillside as a sacrifice to the local dragon.
It's late, it's cold, and it's raining, and Alys can think of only one thing--revenge. But first she's got to escape, and even if she does, how can one girl possibly take on an entire town alone?
Then the dragon arrives--a dragon that could quite possibly be the perfect ally. . . .
