Perhaps the most controversial superhero storyline in the past ten years, Spider-Man's "One More Day" polarized fans with Mephisto-powered reality warpage intended to unclutter the Webslinger's current continuity in one mysterious, marriage-stopping, Aunt May-saving swoop. The comics crowd (ourselves included) have had some theories on how the Marvel Universe really changed when this went down, but the publisher is finally filling in the details themselves with "One Moment In Time" starting in July's "Amazing Spider-Man" #638.

Here's how Marvel describes the storyline's kick-off:

ONE MOMENT IN TIME Part 1 & 2 The questions have been haunting readers throughout Spider-Man's Brand New Day and now the answers are here in four double-sized issues! What really happened at the wedding of Spider-Man and Mary Jane? What does Mary Jane know about Spider-Man today? How did ONE MORE DAY affect the Marvel U? Joe Quesada and Paolo Rivera are here to pull back the curtain and fill in every blank...but the answers may come at a cost to all that Peter Parker loves. This 4-part arc will hold answers, resolutions, and set up the course of Spider-Man's life for years to come... ...and all will be revealed with a whisper. And in Part 2, it's Mary Jane's turn to come clean. What secrets has she been keeping? And who REALLY saved Aunt May? You may think you know the answer, but you're about to find out the truth
