Evil scientists are still trying to convince Max that she needs to save the world, this time by providing the genetic link in speeding up the pace of evolution. Worse, they're trying to convince her that her perfect mate is Dylan, the newest addition to the flock. The problem is that, despite herself, Max is starting to believe it. Fang travels the country collecting his own gang of evolved humans, but the two separate flocks must unite to defeat...

Max boldly navigates post-apocalyptic regions with her broken flock in search of answers about what has happened to their world.

The danger mounts just as Dylan has finally worked his way into Max's heart--and just as her beloved Fang unexpectedly returns to the flock. An explosive confrontation between the two boys with a claim to Max's heart ensues, and the entire world hangs in the balance.

When millions of fish start dying off the coast of Hawaii and something is destroying hundreds of ships, the government enlists Max and the flock, a band of genetically modified children who can fly, to help get to the bottom of the disaster before it is too late.
