Even for annuals, I haven't been impressed much with DC's New 52 annuals, but as a longtime fan of both Barry Allen and Hal Jordan I had to pick this one up. It might be missing Manapul's art, but the I enjoyed the banter between GL and the Flash quite a bit as we get a flashback to their first meeting as well as their latest adventure that gets them pulled back to Arena World. The idea of how the Flash was able to use super-speed to learn how to use the ring as well as how much the force of will took out of him were also well-handled. The back-up story feels mostly like filler, but fans of GL and the Flash (especially the two together) should enjoy this one.
