The listing, Remnants Aftermath (#12) by K. A. Applegate has ended.
This is a brand new paperback.
Earth has definitely changed since the Rock hit it 500 years ago. The world doesn't even revolve anymore. On one side: an unbearable hot, arid, unyielding desert with boiling seas and no relief. On the other: a vast, pock-marked plain of freezing-cold eternal darkness. The Remnants are trapped in a narrow strip between the two deadly plains, with nowhere else to go.
But there is more to this devastated Earth than meets the Remnants' eyes. There are people underground. Humans. And they've been watching Jobs and the others' every move. Now the question is: Will Earth's current inhabitants accept those from the past? Or will the Remnants become as extinct as the planet they once knew?
