Soon the tyrant owl Bylyric will rule over everything, and no honorable owl will be safe. Only the small owl from Stormfast stands between Bylyric and total victory. Lyze is not very impressive to look at, but he has a wild idea for a snake and owl strike unit that just might give the soldiers of the Kielian League the edge they need.This is his story, the story of an ordinary owl who rose to become Ezylryb of the Great Tree. This is the story of what it takes to make a Guardian of Ga'Hoole.
