Thought this section was for BSC fan fiction? Harry Potter has nothing to do with the BSC. :/
It would be if it were a crossover.
I started a BSC/HP fanfic where the BSC has a reunion in their early twenties in Salem, Massachussetts one chilly November weekend and meet some of the Harry Potter characters there who are on retreat.
The BSC is four years older than Harry and company, but the BSC girls and the HP main six characters...Harry, Ron, Hermione, Ginny, Neville and Luna...bond.
