The sky has been counting down. We were too busy to notice.

It starts as a signal from the dark between the stars: faint, exact, arriving a little sooner each time. The few who understand it begin to disappear. The powers who deny everything begin, quietly, to prepare.

Then the leaving begins — outward into the black, toward a world of red dust where something new fights to take root, and something old refuses to let go.

No one will name what waits at the end of the countdown. They only build, and hope, and run out of time.

The Shift is a sweeping epic of hard science fiction: launch windows and tonnage, collapse and rebirth, and the question of who gets to decide who leaves. For readers of Neal Stephenson's Seveneves and Kim Stanley Robinson's Red Mars.

Book One of the Pollux Series.
