The Flash, Volume 7: Savage World — Robert Venditti

The Flash�s life is about to be completely upended! A future version of Barry Allen has managed to seal a rupture in the Speed Force, but there are unforeseen consequences to his actions. While Future Flash remains in the present day, his bewildered counterpart is pulled through the rift, becoming trapped in the Speed Force itself! Assuming the life he had already lived, future-Barry sets out to fix the mistakes he made the first time around. Experiencing those failures has twisted him into a Flash that's far more violent-and deadly! This Future Flash is guided by a warped view of justice-one that would see those who take a life repaid in kind. Collects THE FLASH #36-40 and SECRET ORIGINS #7.
