I have found that the best, and most detailed fanfiction to be found for this couple is done によって Ms-Figg on fanfiction.net. She also has a website called the burningpen.com but it is hard to navigate. Her fics are really good but also explicit. So read with caution if あなた are not into that sort of thing.

Her fanfiction ranges from diferent themes and topics. From ヴァンパイア (featuring a gay vampire named Adam Sweetmeats in 愛 Bites) to a raw primordal power that belongs to hermione ( a bit of Lucious thrown in there). There are some where she is with child, some where there is not. But all of them are really good!

あなた can never really get bored with them because they are never really the same. And plus they stay true to how they were ment to be when they were written.

Look her up!
