Author has written 8 stories for Harry Potter.
So far, there are four stories in my next generation series. They are solely based on the books. Pieces of information that J. K. Rowling revealed afterwards are ignored.
The suggested reading order is as follows:
"Of Hats and Girls"
"Ravenclaw. Ravenclaw? Ravenclaw!"
"Of Boys and Spells"
"Here's To Friendship"
"Exile", unfortunately still not finished, is the link between the books and my next generation fics.
"After The Flight" is an alternative to DH, but fully consistent with the first six books.
The one shots "Power the Dark Lord Knows Not" and "Colours United" are consistent with the books up to OotP, but take another turn from there on.
Incidentally, "Colours United" is the first fanfic I ever posted anywhere. It's never been proofread because there were no beta readers here on ffnet in 2005. I'd be grateful if somebody pointed me to the mistakes that are doubtlessly in the text.
