Marvel are releasing a OGN by Mark Waid and James Robinson set before Superior Spider-Man that deals with Peter's long lost sister Teresa.
In Family Business, the Kingpin is organizing a large crime syndicate and it's Peter Parker, not Spider-Man, who finds himself under attack, Waid says. The ruthless supervillain has "finally decided to expand his criminal empire on a global scale — if Spidey can't stop him."
But before Peter can figure out who's after him, a mysterious woman in a convertible screeches to a halt in front of him, and she tells him she's his long-lost sister, Teresa. The two of them never knew anything about each other, but Peter hops in the car anyway to get the bottom of the situation.
