Hermione Granger and the Perfectly Reasonable Explanation

In 1991, a child came to Hogwarts School of Witchcraft and Wizardry with obvious gifts, but which few suspected would change the world... Oh, and Harry Potter enrolled that year as well. *** A few tweaks to canon, plus extrapolating Hermione's apparent intelligence realistically. I expect events to diverge fairly quickly. ;) *** cover image cc by-nc RooReynolds @ Flickr
