One good knight
(Book)

When George, the Good Knight, arrives to save Princess Andromeda from the dragon for whom she is to be a virgin sacrifice, he does not exactly defeat the dragon, and he and the princess must join forces to find the dragon's lair and destroy it. Traditionally, marauding dragons are soothed only by a virgin sacrifice. And so practical-minded Princess Andromeda reluctantly volunteers to do her duty, only asking for a sword to defend herself. Well, her offer is accepted, but the weapon isn't forthcoming, and so Andromeda faces the dragon alone. Until a Champion arrives to save her-sort of. Sir George doesn't quite defeat the dragon but as Andromeda finishes rescuing herself, she discovers that beneath the Good Knight's well-meaning though inexperienced heroics lies a further tale. Still, Andromeda can't leave her seacoast country in further jeopardy from the dragon's return, and so she and George join together to search for the dragon's lair.
