Relates five adventures of Owl.

"Enraged by his clash with Soren and driven by and all-consuming desire for power, Kludd and his group, the Pure Ones, launch an attack upon the Great Ga'Hoole Tree. The noble owls who live there must fight fiercely to protect their resources and defend their honor."--p.4 cover.

When Soren, a barn owl, arrives at St. Aggie's, a school for orphaned owls, he suspects trouble and with his new friend, a clever elf owl named Gylfie, embarks on a perilous journey to save all owls from the danger at St. Aggie's.

Owl and Rabbit are good friends and neighbors atop a hill, but when Rabbit's garden blocks Owl's view of the forest Owl builds a higher house, which prevents sunlight from reaching Rabbit's plants.

In this prequel, Ezylryb the Screech owl recounts the story of his life in the Northern Kingdoms--his rise through the ranks of the Killian Army, his brother's betrayal, and his friendship with Octavia the snake, to finally become a Guardian of Ga'Hoole.

Poppy the deer mouse urges her family to move next to a field of corn big enough to feed them all forever, but Mr. Ocax, a terrifying owl, has other ideas.

Bear and his friends persuade a bashful owl to play with them.

"Orris the rat lives alone in an old barn surrounded by his treasures, until the day his solitude is disrupted by a sudden flutter of wings and a loud screech. A small owl has gotten caught in a trap in the barn. Can Orris 'make the good and noble choice' (as the king on his prized sardine can might recommend) and rescue the owl, despite the fact that owls and rats are natural enemies? And if he does, will he be ready for the consequences?" -- Provided...

Having a Bloomtastic Festival at school to celebrate spring is a great idea--but Eva Wingdale, a young owl, discovers that it is also a lot of work, and there is nothing wrong with asking her friends for help.

"Soren's sister, Eglantine, si falling under the spell of a strange nightly dream. Then, just as Soren notices her trancelike state, Eglantine disappears, and the dreams become a deadly waking nightmare that puts the Great Tree of Ga'Hoole in terrible danger."--P. [4] of cover.
