In these stories from THE FLASH #52-57, Barry Allen races to the House of Heroes at the center of the Multiverse to meet with the Flashes of 52 worlds for info on the new forces he's recently encountered. Meanwhile, in Central City, Trickster's turning informant against Warden Wolfe, but that brings about a sneak attack that Barry and the time-lost Commander Cold must team up to stop-if they can quit butting heads long enough to do so.
