In the time of the Inquisition, it is dangerous to make many claims at all. Priests, commoners, and kings alike are on the watch for heresy in any form. So that would make it a bad time to, say, begin worshipping a dog, claim she's come back to life, or to have visions of the future that you can't control.
But, that is just what happens to a peasant girl named Jeanne. It's also a bad time to be so strong you break benches to pieces with one blow like William or to be a Jew who can heal with the power of prayer like Jacob.
Brought together by fear and bad luck, kept together by a strong sense of duty and love for the people around them, these three children brave the fanaticism of the Inquisition with bravery, honesty, and virtue--but is that enough to save them from a king who commands a hundred knights?
