The series was planned to end after the tenth book, with the author's blog, Weird New Worlds serving as the continuous adventures with weekly 'chapter' installments. The first three trilogies were released over the course of 1998 to 2006, with a standalone saga serving as a conclusion to the first two ages of flight and a beginning to the third released in 2009. The series is notable for its flora and fauna, along with the maps of various locations in The Edge. The power of flight is a major theme of the books, with each age defined by the current technology used for air travel.

Then, floating wood was used, and finally phrax-power. In The first age, floating rocks were used to stay airborne but then stone sickness, which made the rocks crumble, hit. The series covers a 600-year period, divided into three 'Ages of Flight'. The majority of books are grouped into sagas, with each saga focusing on one character. The stories of The Edge Chronicles take place in the fictional world of The Edge, a vast cliff with no apparent bottom. The series was originally published by Doubleday, a subsidiary of Penguin Random House, and has sold more than three million copies, according to its publisher. It consists of four trilogies, plus four additional books, and other books related to the universe (The Edge).

The Edge Chronicles is a children's fantasy novel series written by Paul Stewart and Chris Riddell.
