In A Blink (Marauders Era)

It's 1976, and the Wizarding World is changing in the blink of an eye.
Finally free from silence, Lark Riddle doesn't know what to do with herself. Her older brother, Tom, is breathing down her neck from hundreds of miles away every moment, and she just might snap under the pressure. With a mother who birthed her into the worst-case-scenario and a father who has yet to be discovered, she feels as though there's no longer a net to fall into if she crumbles to the ground...because she's never felt love, and has a sneaking suspicion that she may be unable to. She's left her old friends, Severus Snape and the notorious Black sisters in her wake, and has yet to move on to bigger, brighter prospects: the Marauders.
Sirius Black has more than enough on his shoulders. While he makes every move he can to stay away from his psychotic ex-family and their allies, rumor has it that there's a war on, and he'll be playing a bigger part in it than he expected. Though this talk of fighting and standing up for what's right is all so thrilling, he has a life, a reputation, and an education to uphold (and all three seem to be plummeting to certain doom at terminal velocity). Lark knows what it's like: feeling alone and living in a world of darkness where the only light is the hope that she can provide for herself, whether it's real or not, and chances are that she may be the only person who will ever make him feel the way that he does when he's around her.
