Barry Allen has just woken up in universe where nothing is the way he left it! Writer Geoff Johns (Blackest Night, The Flash: Rebirth) and artist Andy Kubert (Dark Knight III: The Master Race) team up to put The Flash in a race across time to save the universe.
When Barry Allen wakes up at his desk, he discovers the world has changed. His mother is alive and old allies are now strangers. It's a world on the brink of a cataclysmic war - but where are Earth's Greatest Heroes to stop it? It's a place where America's last hope is Cyborg, who's attempting to gather the forces of The Outsider, The Secret 7, S!H!A!Z!A!M!, Citizen Cold and other new and familiar-yet-altered faces! It's a world that could be running out of time, if The Flash can't find the villain who altered the timeline!
