Countdown September, Book 9, (Paperback)

COUNTDOWN
It's 1999.
The Earth moved. Really.
SEPTEMBER
Only the strongest teens have survived. But now Earth is crashing and crumbling down around them, advancing -- piece by piece -- toward a final, grinding halt.
It can be stopped. There is a key -- a key that can save the world from total annihilation.
If it doesn't fall into the hands of she who has been chosen...to kill them all.
