Harry Potter & the Methods of Rationality
Eliezer Yudkowsky
An enjoyable, funny fic that explores the premise, "What if Harry Potter had been raised by scientists?" Far more emotionally affecting than my memory of the originals, though admittedly I haven't read those in years. There are points that drag (expected from a work this long) but it's surprisingly pacey and readable. I was expecting to hate this, and I didn't: take that for whatever it's worth.
