Harry Potter and the Methods of Rationality

From the introduction: The date is the 24th of July, 1991. Just a little under ten full years ago, the Dark Lord Voldemort vanished from the face of the earth, and his slaying was attributed to little Harry James Potter, now known as Harry James Potter-Evans-Verres. This child has grown up the adopted son of Petunia Evans-Verres and Professor Michael Verres-Evans, and is every inch the bibliophile that his adopted father is. In just a few short days, they will meet Professor Minerva McGonagall of Hogwarts School of Witchcraft and Wizardry, and in a scant few weeks more young Harry will begin his education at Hogwarts... as will you.
