"Central City is quiet. Too quiet. The colorful criminals who make up the Flash's legendary Rogues Gallery--Captain Cold, Mirror Master, Weather Wizard and Heat Wave--are nowhere to be found. But the Fastest Man Alive still can't slow down for a second, because each step he takes toward tracking them down leads him deeper into their deadly trap. And behind it all, an even darker presence looms. A darkness so great that not even the span of centuries can keep it from returning again and again to destroy the lives of Barry Allen and everyone he cares about. A darkness named Eobard Thawne...the Reverse-Flash. To defeat his nemesis, Barry must count on his best friend, Green Lantern; his old foe, Captain Boomerang; the love of his life, Iris West; and his estranged partner, Kid Flash. With all his greatest enemies arrayed against him, has the Flash run out of time at last?"--Back cover.
