The Meridian Paradox

A traveller opens his eyes to a world that has already ended: ash on the wind, silence where cities once stood. He knows the cause. It began with a single choice, and the choice was his. Now he must slip backward through time and stand in the shadow of his own past, because the man he used to be is coming to erase a visionary whose work the world could not survive without. To save what remains of tomorrow, he must stop himself.
