Sixth title in a mythic adventure series in which the heroes are owls! A great battle looms. In preparation, Soren and his band must fly to the mysterious Northern Kingdoms to find allies and study the grim art of war. Meanwhile, St Aggie's has fallen to the Pure Ones. If they are not stopped, they will launch another more deadly attack against the great tree -- and without allies from the north, Ga'Hoole will surely fall. The coming conflagration will demand bravery and sacrifice from all the owls of the great tree. But from Soren and his friends, it will demand nothing less than heroism!
