Awesome story third in the Brane of Extraordinary Women, you really need to read the first story League of Extraordinary women for some of this to make sense. When Alex returns to her dimension she takes the advice of the other heroes to heart and decides that she is ready to take that final step. To do this she searches for the counterparts of the people she met and once she drags the shy but highly intelligent computer genius into her secret world the rest starts to fall into place. Meeting Colonel Jack O'Neill with the Superpower Research Institute along with Finn and Graham she has the beginning of a fixed team to take on the world. Then she meets Hermione, Ron, and Harry and suddenly she is international and now there are characters from all over the place making an appearance, Batman, Firestarter, Hanna to name only a few. The characterization is believable and people being brought into this world are done in such a way that you feel like they were always there.
