The can't-miss crossover adventure continues in New York Times bestselling author Barry Lyga's The Flash: Supergirl's Sacrifice as Supergirl and the Flash team up to save the multiverse. 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. Picking right up from Green Arrow's Perfect Shot, this action-packed follow-up promises to be one of the most exciting reads of the season as Supergirl and Superman join in on the crossover fun.
