From Geoff Johns and Ethan Van Sciver, the visionaries responsible for the blockbuster GREEN LANTERN: REBIRTH and THE SINESTRO CORPS WAR, comes an explosive and jaw-dropping epic that reintroduces Barry Allen, the modern age Flash who single-handedly birthed the Silver Age of comics! While Barry figures out his place in the DCU - from which he's been absent for a number of years - a major threat surfaces and a whole new era for The Scarlet Speedster is begun. This is the starting line for readers old and new!
