The Siege

Fourth title in a mythic adventure series in which the heroes are owls!

In the owl kingdom, a war between good and evil is raging. On one side, Soren and the noble owls of the Great Ga'hoole tree. On the other, Soren's fearsome brother Kludd, who wears a terrifying metal mask to cover his battle scars. Driven by an all-consuming lust for power, Kludd leads his forces in a brutal attack on the Great Ga'Hoole Tree.

Meanwhile, Soren is asked to lead a mission back to the one place he never wanted to see again - St Aegolius Academy for Orphaned Owls. He and his crew will have to enter St Aggie's as spies, then leave without being noticed. . . or caught.

Soren escaped the rocky confines of St Aggie's once. If the Ga'Hoole tree is to be saved he must do it again. . .
