I Just finished identity crisis and the infinite crisis comics which i must say were very entertaining. But what comic do i get next if i want to follow the story line of the justice league?? My friend mentioned something called "52" and told me to read that to follow the storyline, but what is that? is it a new series called 52? or issue 52 of something? Also, any recommended further reading to enlighten my about the justice league members would be nice. thanks.
