When the peaceful future city of Seattle is interrupted by a storm of invading giants from another world, Harlan Ule is but a boy. When he grows into a man, the world has been transformed by the desperate struggle against the invaders. But a scientific breakthrough gives the resistance the chance to go back in time and prevent the alien conquerors from ever finding Earth to begin with.

If Harlan Ule takes on that challenge, he leaves behind his wife and two children and everything he's ever known. And he may never find out if he succeeded, or if his children would be even born once he changes the past to save the future.

Can Harlan Ule travel into the past and stop the invasion without making it worse, and without breaking time itself?
