Read or Die
Description: R. O. D (Read or Die) is about a substitute teacher, named Yomiko Readman (codename: The Paper). Her house is filled with books. When she's not teaching, she spends her free time searching for more books to fill her collection. This must sound pretty boring, but really, Yomiko is a secret agent for the Royal British.
