If you haven't read Deathly Hallows yet, don't follow these links until you do (unless you're interested in all the post-story stuff and not caring much about spoilers).
Three. The first post-DH fic that I've seen. "Three" details the three funerals of the four major deaths in that final set of battles. Absolutely beautiful and breathtaking.
THE web-transcript with Jo. Jo answers manymanymanymany post-Epilogue questions from fans, and a few other nagging things (like the matter of the person who would do magic "late in life"--she changed her mind by Book 3, and so the person never actually existed. Ha.). We hear more professions and more families made. Also, for all the Hufflepuffs out there, she details the Hufflepuff dormitories, what Dudley possibly saw when he saw the Dementors and how that may have sparked how he was in the seventh book, what event triggered each horcrux, Dumbledore's boggart, how muggleborns get magic, how a couple of the deaths we didn't get to "see" in battle occured, and a LOT of other things. She also said to keep on eye on her site because she'll work on posting more answers over time.
