It is 65 million years ago, during a cataclysmic moment in the earth's evolution, and Dusk, just months old, has no way of knowing he will play a pivotal role in creating a new world. What he does know is that he is different from the other newborn chiropters. Not content to use his large sails to glide down from the giant sequoia tree, Dusk discovers that if he flaps quickly enough, he can fly. But this strange gift that makes him feel like an outcast from the colony will also make him its saviour. After most of the colony is savagely massacred by the felids - the earth's first mammalian carnivores - Dusk must lead his fellow chiropters to a new home, and a new life.
