Alex is the younger sister of the famous billionaire Tony Stark, but no one knows about her. At least until now. Today is the day that all that is about to change as she finally becomes a member of the Avengers and gets to go side by side with them on all sorts of adventures. Author's note: I'm currently reworking this story and changing a few things so please don't mind if there are some inconsistencies. The rights to all characters except Alex Stark belong to Marvel.
