It IS a sequel
(SPOILERS, SPOILERS EVERYWHERE. THIS REVIEW IS INTENDED FOR PARENTS WHO DO NOT PLAN TO READ THE BOOK, AND ARE REVIEWING IT FOR THEIR CHILDREN)
First of all, you absolutely MUST read the first book, and remember most of it, BEFORE reading this book. Now that that's out of the way, onto the review. This book gives us the question not answered in Unwind. The WHY. And the whole big reason is TEENAGE REBELLION, and justified teenage rebellion at that. The public school system is shut down. Kids are out of school, out of jobs, and on the streets. They petition, they ask, they try to find away to fix this, but they are ignored. They're teenagers, they get angry, they lash out. But the anger doesn't die, it just keep building. Clappers are born. Depressed, suicidal teenagers are angry, and get determined to take as much of the world with them as they can when they die. They alter their blood composition to make it explosive. They blow up. The world is in chaos. War breaks out. People want to kill these teens, who cannot be controlled. Others say life is precious. And the Heartland war ensues. Everyone wins. Everyone looses. The Unwind accord is made and everyone is happy, except the teenagers, the people who started the problem in the first place.
