Augie and the Green Knight is an adventure story about a scientifically precocious young girl in a world of fantasy.

Augie and the Green Knight is a retelling of a famous medieval romance. The original story is about King Arthur's court encountering a strange giant Green Knight and the quest that follows. In this book, we get to hear the Green Knight's side of the story through the lens of a young nerdy girl named Augie.

Augie is an expert in biology, math, and a bunch of other subjects that adults find boring. She goes off one morning for adventure, only to find herself in a strange world of fantasy. There, she has to use all of her intelligence to save a brave knight from death.
