An all-star creative roster brings you an all-new Marvel event! In a world of unlikely heroes, Dennis Sykes is about to become Marvel's unlikeliest. Banker by day, struggling parent by night - and unhappy about it all. But when a tragic turn of events gives Dennis a 30-day death sentence, he discovers his accident comes with super-powers. And as the weeks in Dennis' life tick down, he sets out to leave a mark one way or the other - even if he has to go through Spider-Man, the Fantastic Four and the Avengers to do it.
