The story of Up the Fall takes place in both Portland and a mythical other world. When the nefarious Graeae Sisters kidnap the three animal spirits that are responsible for the passage of time, the world’s salvation falls into the hands of Diana, a young disabled woman living in Portland. Together with a squirrel spirit named Ratatoskr, Diana travels to this land in order to help save it. Many of the elements of the story were inspired by Japanese, Chinese and Native American mythology.
