A Flash of Flames, and He Was Gone by BlenderChicken reviews
Leo Valdez was the average demigod with wicked fire hands and a place in the Camp Half-Blood Hall of Fame for Most Tacos Eaten in One Minute (8.5). What he didn't expect was to be whooshed away by a blue-and-black speedster, taken to Earth-1, and instructed to capture and deliver the Flash. Why? Because Zoom's story made sense: he was the good guy...and the Flash was not.
