Elseworld's Finest: Supergirl & Batgirl #0

A beautiful Prestige one-shot introduces the finest team of a world you never imagined! In an Elseworld where Supergirl was raised by Wonder Woman and the Justice Society, and Batgirl is a vigilante who keeps Gotham City safe from villainy and super-beings, there could never be two more different super-heroines. But when the love of Supergirl's life--her benefactor, Lex Luthor--is kidnapped by the Joker--a bulked-up loser obsessed with Batgirl--the champions of Gotham and Metropolis form a reluctant partnership...and discover the horrifying secret of the Girl of Steel's origin.
