Poor Creel. She can't believe her aunt wants to sacrifice her to the local dragon. It's a ploy to lure a heroic knight so that he will fight the dragon, marry Creel out of chivalrous obligation, and lift the entire family out of poverty. Creel isn't worried. After all, nobody has seen a dragon in centuries.

But when the beast actually appears, Creel not only bargains with him for her life, she also ends up with a rare bit of treasure from his hoard, not gold or jewels, but a pair of simple blue slippers—or so she thinks. It's not until later that Creel learns a shocking truth: She possesses not just any pair of shoes, but ones that could be used to save her kingdom, which is on the verge of war, or destroy it.
