Collection: JLA: World Without Grownups

The heroes of the DC Universe find themselves separated by a mysterious force that introduced DC's newest super-team, Young Justice. A boy receives a gift from his father and somehow triggers a force that puts all the 16-years-old-and-younger humans on one Earth and the adults on another. As the JLA searches for an answer to the mystery on one world, Robin, Impulse, Superboy and other heroes try to keep a kid-ruled world from falling apart.
