Gammage Cup — Carol Kendall

The Minnipins have lost their past. Long ago, the hero Gammage led them in war against the horrible Hairless Ones. But now -- Bravery? Forgotten. Courage? No more. Heroes? The stuff of storybooks.
Yet sometimes heroes turn up when they are least expected....

Muggles, Gummy the poet, and Walter the Earl are not like the other Minnipins. They dress differently, speak their minds, and -- when Walter the Earl finds a package of old scrolls and swords -- dare to disagree with the Minnipin leaders. For their troubles, they are banished from their village.

But Walter the Earl found the weapons for a reason: The Hairless Ones have returned. And this time there is no Gammage to protect the Minnipins. This time there are only Muggles and her friends, outlaws who must rescue the very people who have cast them out.
