Walking with Superman: Day 326

Superman's walking along the Eleven Point River near Black Rock, AR, when he's divebombed by a familiar figure in a purple-and-green battlesuit! The Man of Steel braces himself for the next flyby, but when he gets a good look at his enemy, he's shocked to see that Lex Luthor has apparently become a woman! Somehow, Superman has been transported to an alternate Earth, and while Leslie Luthor doesn't pose much of a threat, the missing Superwoman's allies in the Justice League may not be so forgiving! Meanwhile on our world, a bewildered Superwoman finds herself face-to-face with the sinister force who orchestrated this dimension-swap--but will the mysterious villain prove too strong for the Woman of Steel?
