Guardians of Ga'Hoole is a children's fiction book series written by Kathryn Lasky and illustrated by Richard Chowder. There is also an upcoming movie of the same name, based on the series. Most of the main characters are owls, and the series is a cross between animal fiction such as Watership Down and epic fantasy.  In the October/November months of 2008, the main series ended with fifteen books, the most recent book in the series being The War of the Ember. However, the series will continue with more accompanying books, including the already-released Guide Book to the Great Tree and the upcoming book Lost Tales of the Great Tree - a sneak peek was provided at the end of book fifteen. The accompanying series is written by Kathryn Huang Knight.
