A/N This is not a good reference for how to play basketball as my knowledge of it mostly comes from High School Musical.
Hermione had been forced into basketball club when her parents realised that although she didn't particularly like playing and much preferred spectating, she was pretty good at a fair few sports. Now, those after school clubs seemed to have paid off as her and Ginny were whooping the boys asses in a friendly game at Hampstead Heath. Ginny was also a more than decent player naturally, and the boys were more talented at broomstick sports than ball games.
Scoring another three pointer, Ginny took pity on them and passed the ball to a slightly out of breath Harry. Taking a risk he went straight for a jump shot. The ball bounced off the rim, over the top of the backboard and into the undergrowth.
Attempting to stifle a laugh, Hermione jogged past a bewildered Harry throwing him a cheeky smile, and after the ball. They had chosen to magically construct a court here at the beginning of the summer as it was nicely out of the way of the public paths, although they still had to be careful using magic.
Still looking for the ball as she brushed aside branches and attempted not to disturb the wild plants, Hermione was distracted by one deep purple flower in particular. Its petals seemed to be tipped with black, and twisted out from the stem in soft curls. Avoiding a patch of nettles she stepped closer to get a better look, not noticing the ball that was half hidden in a nearby bush, nor the fairy ring she was about to step into. Her foot landed in the confines of the mushroom arc and she was instantly swept away, still in the awkward semi-crouching position she had leant into to get a better look.
Bellatrix had been minding her own business and practising wandless magic in the Black Manor gardens when a strange girl had stumbled out of thin air in front of her.
"Who are you?"
