I Solemnly Swear - a Fifth Marauder Story

Brianna Mae Scamander did not appreciate Sirius Black flirting with her on her very first night at Hogwarts. After a while of attempting the method of polite rejection, Brianna gave up and hexed him, causing Sirius mortal embarrassment and a desire for revenge. James, never one to turn down the opportunity to prank someone, agreed with the idea. The Marauders congratulated themselves on time well spent, but never were they expecting Brianna to prank them right back... And then a certain werewolf catches the new girl's eye...

And thus begins a tale of mischief, friendship, the power of love against all odds, and just a bit of magic.
