A fanfiction made by Creator/ShadePenn exploring the "What if..." category with just how much one thing that no one ever notices in the first run of ''ComicBook/SpiderMan''. So the question is:

[[ArmourPiercingQuestion What if the spider that bit Peter was female?]]

This fanfic explores just how much of a change that one little detail could make in the world of Spider-Man. Found [[http://www.fanfiction.net/s/8092152/1/Blessing-In-Disguise here]]. The story was uploaded in 2012 and counts six chapters, the last one uploaded in 2013. It is incomplete.
