among other dark things {hp}

When James Potter gives up his youngest child, ostensibly for her own protection, Sirius Black knows that his friend has changed - and not for the better. And he isn't going to just sit back and watch. Taking up the mantle of Lord Black, Sirius adopts his goddaughter, taking her away from the abusive muggles she had been trapped with.

Now Hollis Black, formerly Holly Potter, is ready to start her first year at Hogwarts. Raised in Number 12, Grimmauld Place by her two dads, Padfoot and Moony, as the heir of House Black, she's more than ready to show the world that she's worth more than the Potter's ever thought. Even if it means going to school with Lucas Potter, her twin brother and the famous Boy-Who-Lived.

Hogwarts is just as amazing as her dads told her it would be, and Hollis is eager to learn magic. But the mystery of the third-floor corridor is one that she might not be able to resist. And why is Professor Quirrell staring at her, anyway?
