A great cold has seized the Beyond. The warmth of summer, the smell of sweet grass, and the great caribou migrations are distant memories. Now the wolves know only ice, dark, snow, and endless cold. The order that kept the wolf clans strong for thousands of years has broken down completely. The wolves have only one chance for survival. They must find their way to a new land, a land of warmth and summer. But the journey will take them over a frozen sea and through thousands of miles of perilous territory. Will the wolves trust young Faolan to lead them?

Soren and his band are sent to the mysterious Northern Kingdoms to gather allies and learn the art of war in preparation for the coming cataclysmic battle against the sinister Pure Ones. Meanwhile, in the Southern Kingdoms, St. Aggie's has fallen to the Pure Ones, and they are using its resources to plan a final invasion of the Great Ga'Hoole Tree.

In the midst of war, Soren's sister, Eglantine, unwittingly becomes a spy for Kludd, leader of the Pure Ones, a group of evil owls. She is brainwashed by an owl sent by the Pure Ones to infiltrate the Great Ga'Hoole Tree. Her odd behavior eventually attracts attention, and Soren and his friends vow to find out what's wrong with Eglantine. They ultimately learn what happened and help her reverse the effects of the brainwashing.

Soren's beloved mentor, Ezylryb, is finally back at the Great Ga'Hoole Tree. But all is not well. There's a war between good and evil in the owl kingdom. On one side is a group led by Soren's fearsome brother, Kludd, who wears a terrifying metal mask to cover his battle-scarred face. On the other side are the owls of the Great Ga'Hoole Tree, who must fight to protect their legendary tree from Kludd's attacks.

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 is Soren's life, but she's been through an ordeal too terrible for words. Deep within Soren's gizzard, something more powerful than knowledge tells him there's a connection between these mysterious events.

Soren is born in the forest of Tyto, a tranquil kingdom where the Barn Owls dwell. But evil lurks in the owl world, evil that threatens to change Soren's life forever.
