Everything—their families, their friends and teammates, their very galaxy—gone in a blinding flash of light. Upon preventing a cataclysmic rift in their universe, several members of the 30th century's famed champions, the Legion of Super-Heroes, find themselves stranded an inconceivable distance from home, with no devisable method of safe return. Before they can even attempt to return to their galaxy, however, the Legionnaires must first endure the unknowns of a hostile galaxy plagued by the alien Progeny, whose godlike creator deems diverse species impure "variants" subject to eugenic "deletion." It is these encounters, and their own questionable solutions, that will soon have the heroes wondering if the very purpose of the Legion—powerful individuals from across the cosmos, bound together by a common dream of galactic harmony—has also been lost. Joined by superstar artist Olivier Coipel (The Mighty Thor), who made his comics debut on the series, Abnett and Lanning strand the future's greatest heroes in an unknown galaxy beset with mysterious cosmic threats for epic sci-fi storytelling at its finest.
