Margo Potter & Sherlock Block's Only Regret
The last thing Margo Potter remembers is talking to Tom Riddle in the fall of 1992. But when she wakes up, she finds herself right smack in the middle of the greatest mystery in wizarding history. Adding onto the fact that someone named Sirius Black is on the loose and he's after the Potter twins.
The worst part? More than six months have passed and Margo doesn't remember any of it.
