JLA, book 18 : Crisis of Conscience
Geoff Johns, Allan Heinberg et Chris Batista2006

In the wake of IDENTITY CRISIS, the JLA decides the time has come to tell Batman that they stole part of his memory. But, the League is attacked by the Secret Society of Super-Villains — out for vengeance now that their own memories are restored. As the JLA battles, the Martian Manhunter confronts Despero — the alien conqueror and the one behind the villains' memory-restoration.

By the time the dust settles, the JLA may have won the battle but lost the war!
