Flash Crossover Crisis Hardcover Volume 02 Supergirl's Sacrifice

While the Flash and Team Arrow closed the dimensional rift looming over Central City, they still have plenty of chaos to deal with: Cisco and Curtis are lost in time, thousands of speedster refugees are now stuck on their earth, and a mad bomber is at large. But when Anti-Matter Man arrives on Supergirl's doorstep on her home of Earth-38, it'll be all hands on deck for a team-up of epic proportions to stop him.
