Expedition Unknown

Robin, Speedy, Aqualad and Kid Flash are finally granted access to the headquarters of the Justice League. But when that access turns out to be little more than a glorified backstage pass, Speedy walks, and the other three sidekicks go on a mission of their own.

Robin, Aqualad and Kid Flash are prisoners of Project Cadmus. Their only hope is to help them break free.

The team finds itself wandering the desert of Bialya with no memory of the last six months or of each other. Only Miss Martian can restore their minds and figure out what happened. But is she too late to save Superboy?

Red Arrow's battle to prevent the League of Shadows from inciting a war pits him against the world's most dangerous assassins and allies him with someone more dangerous still. Too bad Aqualad couldn't convince him to ask the team for help.

Batman assigns Superboy and Miss Martian to go undercover inside Belle Reve Penitentiary, a federal prison designed to house the world's worst supervillains.

When the cave itself is attacked, can Artemis and Robin, the two teens without super-powers, save the team or even themselves from the unknown invaders?

Already exhausted and rattled after a home turf invasion of the cave, the team learns Aqualad, their friend and leader, withheld vital information that put them all at risk. When Batman sends the team and new den-mother Captain Marvel to India to investigate bizarre reports of armed animals attacking human beings, can Aqualad pull his fractured team together?
