There is an island in the sky, and not everyone can see it. A harmless village boy living in the rural lands, Iolani Tori is afraid of heights and loud noises. Taken by surprise when he receives a mysterious letter addressed to him, Io finds out that the floating island wasn't a figment of his imagination after all. A talking sparrow; An eagle's eye, A waiting vulture And a silent night.

Ever since an event known as the Disaster, monsters and mayhem rule the world. There are those lucky enough to live inside the Fence, while those who don't, are treated little better than the beasts that they fear.

[Second book of the Flight Series] "More than anything, the sky was red. It wasn't dark, no. Just red." Iolani Tori learns about the part of him that isn't human; and sees the line between animal and himself thin to something less than a thread. If raw aggression, lust, and selfishness prevailed--and if that was what it meant to be human--how was he to not regard himself as a bird that relied on its instincts to survive? Io finds that it is sometimes hard to hold on to his humanity; to be nice, and to be kind. Well apart from that, he also learns that he smells like fresh linen when he's in heat. Weird.
