Guardians of Ga'hoole: Lost Tales of Ga'hoole the Rise of a Legend and the Rise of a Levend [Paperback]

An owlet hatches out onto Stormfast Island and into a world torn by war. For one hundred years, his people have fought off enemy owls from the Ice Talons, but the tide has turned. An invasion is coming, one the Kielian League won't have the strength to resist. 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.
