I'm addicted to fan fiction so I'm really interested in reading your recs. To make it easier to find, could you please provide the fic title, author, link/archive and a summary?

- anything by Fionnabhair (PhoenixSong, SIYE, FanFiction.Net) You must read her fics, they're all beautifully written and her portrayal of Ginny is the best I've ever read

- anything by Melindaleo (PhoenixSong, SIYE, FanFiction.Net) Her style's a lot like JKR's and you should definitely read her chaptered fics

- anything on the H/G Ficafest (link) There are some seriously good fics on this website

- Seeking Ginny by Casca (FanFiction.Net) For years Ginny Weasley has tried to stop her feelings for Harry Potter. She's even uprooted her life. But what happens when it's time to come face to face with him again?

- After the End by Sugar Quill (FanFiction.Net) This is the ultimate H/G epic and a must-read. This was written before OotP came out, so the Ginny in this fic is a little different from the Ginny we're familiar with but she's still very strong and a great character. There's also a lot of focus on Ron and Hermione in this fic, maybe more so than Harry/Ginny

- Exposure by Tosca1390 (FanFiction.Net) The summer after Fifth Year is one filled with grief and confusion for Harry and Ginny. Includes towels, closets, and sins galore!

- The Mechanics of the Human Engine by MagnoliaMama (PhoenixSong, H/G Ficafest) This is a wonderfully written fic about Harry and Ginny working together to fix Sirius' flying motorbike

- anything by St Margarets (PhoenixSong, SIYE) All her fics are fluffy but very real and The New Zealand Chronicles is one of the best fics I've ever read

- In The House of the Quick and the Hungry by Laura S'Mora (FanFiction.Net, SIYE) The finer aspects of Ginny Weasley's life, all entwined, in their own way, within the story of how she wound up with Harry Potter.

I've got loads more but I can't really remember them all right now.
