I Don't Belong (Warren Worthington iii Fanfic)

Vivian Howlett is the younger sister of James Howlett. Both very close siblings living in an abandoned cabin in Ohio.
Growing up for the Howlett's wasn't easy. Vivian never really got to know her parents seeing as they died when she was just a baby. Logan had pretty much raised her and would tell her all kinds of stories about their family and what he was like back then seeing as the age gap was pretty far.
Vivian is a lot like her older brother in some ways, but it other ways she's far more different. When Logan went through his mutant transformation, years later Vivian went through the same transformation...but it's not like the same as her brothers.
Sure, she's got the rapid healing and claws and great senses...but she grew to find out she could turn into a white wolf. She was confused and unsure of how she got the extra mutant ability but Logan had promised to help her control it.
However, things weren't as easy as pie with Vivian as Logan had hoped, whenever she'd be in wolf form, not only was her transforming completely random but whenever she was a wolf, she would lose control as if she didn't know who she or Logan was so Logan had a hard time but this was his baby sister so he did what he could.
But now being 18, Vivian and Logan are trying their hardest to figure out Vivian's mutation and frankly Vivian worries...she's not only scared of what happens when she transforms, but she's starting to get scared of herself...
So what happens when they go to a special school where there's other's like her? What happens next? Does she learn to control the beast inside of her? Will she make friends? Or will she simply not belong?
