The much anticipated prequel to bestseller Wool that takes us back to the beginnings of the silo.

In a future less than fifty years away, the world is still as we know it. Time continues to tick by. The truth is that it is ticking away.

A powerful few know what lies ahead. They are preparing for it. They are trying to protect us.

They are setting us on a path from which we can never return.

A path that will lead to destruction; a path that will take us below ground.

The history of the silo is about to be written.

Our future is about to begin.
