Amelia Sand is a student at Ainsworth Academy, where nonhumans are taught to be "civilized." But for the rulers of Umbra-humans who came through a world-gate from Earth and now sit upon the thrones-that's not enough. When Amelia discovers their plans to use magic to force her and her fellow monsters into blind obedience, she sets out to stop them.

Everyone knows goblins can't be heroes, so Amelia visits a world-gate to find human champions of her own. But instead of mighty young heroes, she gets stuck with two old women who have no interest in magic or fighting.

With her friend Boa (a talking shimmer snake), Amelia joins former teacher Ruth and absent-minded Lily on a quest to save the "uncivilized" peoples of Umbra.

Full of humor and hilarious goblin hijinks, Amelia Sand and the Silver Queens is a story about finding unexpected family and learning to trust in your own power.
