Soren, a young owl, is enthralled by his father's epic stories of the Guardians of Ga'Hoole, a mythic band of winged warriors who had fought a great battle to save all of owlkind from the evil Pure Ones. When Soren and his older brother Kludd fall from their treetop home and right into the talons of the Pure Ones, Soren makes a daring escape with the help of other brave young owls. Together they soar across the sea and through the mist to find the Great Tree, home of the legendary Guardians -- Soren's only hope of defeating the Pure Ones and saving the owl kingdoms.
