Justice League of America, Vol. 1

The members of the Justice League and Justice Society who weren't incapacitated by the Lord of Time's attack hurtle through time now to his lair in a dimension adjacent to 3786 AD, unknowing that their pursuit is part of his plan. He has come to the conclusion that only these heroes, with their resolve tempered by defeat, have a chance of preventing his computer from stopping all of time. But are even these considerable heroes up to the task?
