The Flash — Susan Griffith; Clay Griffith

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 â€" the Arrow.
