What is Infinite Crisis?
Infinite Crisis is the sequel to Crisis on Infinite Earths. Basically, 20 years later, Alex Luthor attempts to restore the multiverse. The 7-issue miniseries has not yet been completed, so this answer will be updated when it has. Post-IC, DC had a “One Year Later” jump in all of their books, and a weekly miniseries titled 52 to cover the OYL gap.
