Before he graduated into the big leagues and became the super-fast, crimson hero the Flash, Bart Allen was the brash, teenaged speedster known as Impulse!

When Max Mercury, the "zen guru of the Speed Force" discovers that his connection to the very energy source that gives him super-speed has been severed, it's up to Bart to find a way to save his mentor and surrogate father. Can Impulse find a way to save Max in time? Or has death finally caught up to the legendary hero? Featuring breath-taking early DC work from current superstar artist Ethan van Sciver (GREEN LANTERN: REBIRTH, GREEN LANTERN: SINSESTRO CORPS WAR)!
