According to Variety, Warner Bros. has acquired film rights to Kathryn Lasky's children's fantasy series Guardians of Ga'Hoole and set it up as a CGI animation film with Donald De Line producing.

"Guardians" is De Line's maiden project for Warner Bros. since signing a three-year first-look deal in April.

Lasky's seven-book series revolves around a parallel universe featuring a cast of owls and magic transformations. The first book begins with a young barn owl being pushed out of his family's nest by his older brother and then being rescued by agents from a mysterious school for orphaned owls.

Lasky will pen the screenplay and exec produce. She's written more than 50 books, including "Marven of the Great North Woods," "Beyond the Burning Time," "Memoirs of a Bookbat" and "A Brilliant Streak: The Making of Mark Twain."
