Maximum Ride and the motley crew of mutant birdkids have been through a lot. From rescuing the youngest of the group from the hellhole where they were created, to a flight for their lives across the country, even going to Germany to put the CEO of Itex, a polluting mega corporation, behind bars. Surely they deserve some downtime, don't you think? Nope.
This story takes place between books 3 and 4 of the series.
