The burning / Lasky, Kathryn

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. Aggies has fallen to the Pure Ones and they are using its resources to plan a final invasion of the Great Ga'Hoole Tree. With the future of all Owldom in the balance, the parliament of Ga'Hoole must decide whether or not to join forces with the brutal Skench and Sporn and the scattered remnants of St. Aggies who remain faithful to them. The coming conflagration will demand wisdom, bravery, and sacrifice from all the owls of the great tree, and from Soren and the band, nothing less than heroism.

Soren and the rest of the band of owls in the great tree must fly to the mysterious Northern Kingdoms in order to prepare for the deadly attack against them, but St. Aggie has fallen to the Pure Ones and without Soren and his allies, their enemies will prevail.
