The premise of this book was quite clever, but Morrow ofet has his characters disobeying rules which he created earlier ni the book. It's worth a read if you liked Morrow's other books.
The concept is simple - no one lies except for those who are trying to escape the typical Big Brother government. It is a short book and is only moderately satisfying. I'd suggest reading George Orwell's 1984 instead of this book if you haven't before.
