Alexandra Prewett {Sirius x Alexandra} | A Marauder's Era Fanfiction

Alexandra Prewett is known for many things: A prankster, aunt, one-third of the Prewett siblings, twin sister of Fabian and Gideon Prewett, little sister to Molly Weasley Prewett, youngest Prewett, and ultimate troublemaker.
However, what she isn't known as is an artist, both musically and artistically. Only her closest friends know that. Growing up, she spent a lot of time with her twins, Fabian and Gideon, but also with her two best friends, Eric and Bryan. She would show them songs and paintings and drawings.
When they went to Hogwarts, no one knew what would happen. But they didn't expect to befriend the classic 'Marauder's' and get caught up in their pranks.
What happens when Alexandra gets close to all of them, especially Sirius, and all her secrets begin to unfold? Will her new friends stay and comfort her from those said secrets, or will they turn their backs and walk away from her?
