My two favorite HP fics are both by sam_storyteller over on LJ.
One (Remus/Tonks) is Amid My Solitude, which was written post OoTP, and managed to guess at Remus/Tonks before it became canon. Lovely, lovely stuff.
The other (also Remus/Tonks) is Cartographer's Craft. This one also has a pairing that might make one go
bwuh?
at first, but that ultimately works, and works well.
There is only one "Harry Potter" fanfic I can take, and it's Harry Potter and the Eagle of Truthiness.
You have seen the Colbert-in-Middle-Earth story, Toddson?
Link, please? pretty please?
A Harry/Colbert pairing?
Not sexual, thank goodness. But it's bloody hysterical.
Between Lorien and Rivendell.
The rated M one at that page called "Shorts Weather" is a tad more disturbing--it's Bill O'Reilly/Colbert (mild) slash!
Harry Potter and the Eagle of Truthiness.
Oh, it's been WAY too long since I looked at that. Love it.
The only non-Colbert related HP fanfic I read is the ongoing project Facilis Descensus Averno, which is dark juicy Slytherin backstory.
Oh, it's been WAY too long since I looked at that. Love it.
I have to bring it up every so often. Just because.
Also, as there are other books out there besides "Harry Potter," I'm almost done with Michael Chabon's "The Yiddish Police Union." Which is a lovely, weird little book.
