I don't read a lot of "alien" books, but I was pretty impressed with how unique a concept this book was. Earth has been settled for a century, with aliens as the governors of the planet. It's been a century of peace but some humans don't like that they aren't "free," and keep trying to incite violence and upheaval. Donovan is an exo soldier, which means that at 6 years old he was given alien cells that help him live longer, protect himself, and better serve the aliens. He's able to armor himself just like the aliens and it definitely comes in handy when he's kidnapped by human terrorists. Donovan isn't sure what they are fighting for. Isn't earth better with the alien overlords? Unique and inventive; this is storytelling at its finest. Perfect for fans of young adult fantasy.
