Sunwing by Kenneth Oppel
Sunwing continues Shade's epic adventure begun in Silverwing. Shade discovers a mysterious human building containing a vast forest. Home to thousands of bats, the indoor forest is as warm as a summer night and teeming with insects to eat. And through the glass roof the bats can finally see the sun, free from the tyranny of the deadly owls. But is this bat paradise all that it seems? Shade and his Brightwing friend Marina aren't so sure. Shade has seen Humans enter the forest and take away hundreds of sleeping bats for an unknown purpose. And where is Shade's father? In this thrilling continuation of Shade's saga, Kenneth Oppel expands the adventure and poignancy of Silverwing and takes it to a new level of excitement.
