The year is 1Q84. This is the real world, there is no doubt about that. But in this world, there are two moons in the sky.

In this world, the fates of two people, Tengo and Aomame, are closely intertwined. They are each, in their own way, doing something very dangerous. And in this world, there seems no way to save them both. Something extraordinary is starting.

Book Two of 1Q84 ended with Aomame standing on the Metropolitan Expressway with a gun between her lips. She knows she is being hunted, and that she has put herself in terrible danger in order to save the man she loves.

But things are moving forward, and Aomame does not yet know that she and Tengo are more closely bound than ever. Tengo is searching for Aomame, and he must find her before this world's rules loosen up too much. He must find her before someone else does.
