The Flash #311

In "Captives of the Boom-Boom-Boomerang!", the Flash finds himself trapped in a time-twisting scheme when Captain Boomerang unleashes a mysterious device that sends the Red Speedster hurtling through history. With help from a surprisingly resourceful Fiona Webb and a cast of unlikely allies—including Colonel Computron, his daughters Francine and Luna, and even a long-dead pirate named Long John—the Flash must outrun both time and treachery to stop a scheme that threatens to unravel reality itself.
