Flash: The Haunting of Barry Allen

An original novel by Clay Griffith & Susan Griffith based on the hit Warner Bros. series created by Greg Berlanti & Andrew Kreisberg & Geoff Johns 

Speeding through Central City, Barry Allen is met with a startling sight—the Flash, older, battered, and badly injured. Before he can speak, the doppelgänger is gone.

Then Barry begins experiencing glitches in his powers—moments that leave him ghostly and immobile in the middle of missions. When a group of his enemies—including Pied Piper, Weather Wizard, and Peekaboo—chooses this time to launch a new assault, the Flash seeks help from his most trusted ally.
Oliver Queen – the Arrow.
