Barry Allen is a hero. His work for the Central City Police Department saves lives, and he has solved numerous criminal cases. As the Flash, he protects the innocent and battles evil. He is the Fastest Man Alive! Or he was...

Barry Allen wakes up to a world that is not his own. A place where his mother was never killed...and the Flash never existed.

The history of Barry's life is not as he remembers it, and the people he cares about most are now strangers, vanished, or worse. This altered universe is on the brink of a cataclysmic war. No human has ever wielded the Green Lantern's light, and no one has ever heard of Superman. Batman has as much blood on his hands as his enemies do, and America's last hope is Cyborg.

Powerless and alone, Barry Allen desperately tries to hold on to his memories of the reality that once was. If there is any hope of setting things right, he must convince this world's strange, dangerous heroes to help him fix what was broken.
