A Bad Day, Or Is It?

When people begin falling ill with an unknown disease that only affects type O-positive blood, Peter must find a cure or, almost better, the people behind it. but the thing is, no one believes Peter when he says that someone unleashed the illness to Queens. But he knows that some one, or something, did this. Besides, he saw them do it.
(I do not own any of these characters, all rights go to Marvel and Sony)
(This is a Peter and Michelle fan fiction, but it won't focus on JUST that, but I can assure you it will be in there:))
