This is a series that follows six genetically altered kids that have 2% avian DNA. Because of this, they have wings. They grew up in a lab living under horrible conditions. Now they are living on their own and taking care of themselves the best they can.
They end up having to save the world and each other. They deal with issues of environmental pollution and the general destruction of the planet by grownups. They do all this while dealing with life as a hormonal teenager (for a few) and just being kids (for the rest).
This is a fantastic young adult series that was a really fun read. I read it on vacation and it was perfect for vacation reading. I'm pretty sure there's one more book slated for the series but it won't be out until next year.
