Yes, I enjoyed the original Harry Potter novels, and the films, and watching Emma Watson grow up, but a fanfic called Harry Potter and the Methods of Rationality has really caught my interest. Author Eliezer Yudkowsky (aka Less Wrong) has not only reacted to some of the common complaints about Rowling's plot, such as Harry being an indifferent student, he has written a story that makes science and reason seem magical and powerful. Yudkowsky's Harry does occasionally sound more like Encyclopedia Brown than Tom Brown:

Dear Deputy Headmistress Minerva McGonagall,

Or Whomsoever It May Concern:

I recently received your letter of acceptance to Hogwarts, addressed to Mr. H. Potter. You may not be aware that my genetic parents, James Potter and Lily Potter (formerly Lily Evans) are dead. I was adopted by Lily's sister, Petunia Evans-Verres, and her husband, Michael Verres-Evans.

I am extremely interested in attending Hogwarts, conditional on such a place actually existing. Only my mother Petunia says she knows about magic, and she can't use it herself. My father is highly skeptical. I myself am uncertain. I also don't know where to obtain any of the books or equipment listed in your acceptance letter.

Mother mentioned that you sent a Hogwarts representative to Lily Potter (then Lily Evans) in order to demonstrate to her family that magic was real, and, I presume, help Lily obtain her school materials. If you could do this for my own family it would be extremely helpful.

Sincerely,

Harry James Potter-Evans-Verres.

... but not always. It is a fanfic, and you can only read as much as has been written so far. For example, after months of waiting, fans can finally read Chapter 78. I've started over from the beginning myself.
