The government wanted superheroes nowhere near the town of Monument Point. More than a mile below it, the JSA and the Challengers of the Unknown learn the what while, on the surface, Wildcat and Green Lantern learn the why. It's all to do with an ancient god who absorbs metahuman powers, setting him up as the final foe to be faced by the JSA in this run.
But that's next issue, let's stick with the current number, which has plenty to commend it. For one thing, there's Marc Guggenheim's sprightly script, which has the JSA and Challs bouncing off one another marvellously. The dialogue crackles as the Challs show that they don't need super-powers to make a difference - they have guts and, more importantly, knowledge. There's precious little Ace, Rocky, June, Prof and Red don't know about history, myth, archaeology, pet grooming ... if the DC Universe had a quiz league they'd be at the top. And the JSA are a lot of fun too, especially married couple Jesse Quick and Hourman.
