Soren, Gylfie, Twilight and Digger go on their quest for the Great Ga'Hoole Tree hoping that this will help them to fight the evil they have left behind and maybe save Soren's little sister. They have to learn how to become a member of the community of the Great Ga'Hoole tree and how to be the best owls they can be. Interestingly this one explains that the humans have disappeared, leaving some buildings behind. You can see the troupe grow and start to think and plan. I'm looking forward to where this is going.
