Guardians of Ga'Hoole Series by Kathryn Lasky

Pushed from his family's nest by his older brother, barn owl Soren is rescued from certain death on the forest floor by agents from a mysterious school for orphaned owls, St. Aggie's. With a new friend, clever and scrappy Gylfie, he uncovers a training camp for the leader's own nefarious goal.

It began as a dream. A quest for the Great Ga'Hoole Tree, a mythical place where each night an order of owls rises to perform noble deeds. There Soren, Gylfie, Twilight, and Digger hope to find inspiration to fight the evil that dwells in the owl kingdom. The journey is long and harrowing. When Soren and his friends finally arrive at the Great Ga'Hoole Tree, they will be tested in ways they never dreamed and face challenges they never imagined... moreIt began as a dream.

Ever since Soren was kidnapped and taken to the St. Aegolius School for Orphaned Owls, he has longed to see his sister, Eglantine, again. Now Eglantine is back in Soren's life, but she's been through an ordeal too terrible for words. And Ezylryb, Soren's mentor, has disappeared. Deep within Soren's gizzard, something more powerful than knowledge tells him there's a connection between these mysterious events. In order to rescue Ezylryb, Soren must embark upon a perilous quest... moreEver since Soren was kidnapped and taken to the St. Aegolius School for Orphaned Owls, he has longed to see his sister, Eglantine, again.

In order to rescue Ezylryb, Soren must embark upon a perilous quest. It will bring him face-to-face with a force more dangerous than anything the rulers of St. Aggie's could have devised-and a truth that threatens to destroy the owl kingdom. less

Tensions erupt in the owl kingdom when the forces of evil wage war against the protectors of good. Enraged by his clash with Soren and driven by an 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... moreTensions erupt in the owl kingdom when the forces of evil wage war against the protectors of good.

The noble owls who live there must fight fiercely to protect their resources and defend their honor. Meanwhile, Soren is called upon by the elders of the Great Tree to lead a mission back to the one place he thought he'd never see again-St. Aegolius Academy for Orphaned Owls. He and his crew will have to enter St. Aggie's as spies, then leave unnoticed once their work is done. If peace is to be restored, he must do it again. less

Nyroc has exiled himself from the wicked Pure Ones. He flies alone, feared and despised by those who know him as Kludd's son, hunted by those whose despotism he has rejected, and haunted by ghostly creatures conjured by Nyra to lure him back to the Pure Ones. He yearns for a place he only half believes in--the great tree--and an uncle who might be a true father to him--the near-mythic Soren. Yet he cannot approach the tree while the rumor of evil still clings to him... moreNyroc has exiled himself from the wicked Pure Ones.
