In 1990 Mark Waid's legendary writing career began when he scripted his first issue of The Flash . Waid continued to work on Wally West for nearly a decade, building a world that would keep the character running for years after Waid's departure to other titles. Under Waid's keen pen, Wally West gained a new depth of character that changed The Flash for good. In this next graphic novel chapter, the ruthless Savitar attempts to take control of the Speed Force, an indefinable energy field that is the source of all speedsters' powers. Learning that every one of his allies, including Impulse and Jesse Quick, has lost their speed, the Flash rushes to take on this new menace. But when the Scarlet Speedster confronts Savitar, he learns that his enemy has diligently studied the Speed Force and can use it in ways that the Flash never dreamed of. Up against a foe who is more than his equal, the Flash's only chance of victory now lies in the desperate self-sacrifice of one of his dearest friends. This fifth volume of The Flash by Mark Waid collects The Flash #106-118 and Impulse #10-11.
