Last string to hold on

Hey guys so this my first time writing a book,
So this story talks about a girl called Rae Larsen , Rae plays everything by her rules and she won't break them now. She's always happy ...or that what it seems like , she's starting to fade away into her mind. Her number 1 rule is not to fall in love not after what her dad did to her mom , so will the rule apply on her brother best friend or not?

Alex carter he's just a normal teenager , or that's seems to be what everyone believes , he trusted one person , Mason Larsen with his secret , his mom made him promise her one thing "don't let the beauty you catch fade away " , every thing is going as planned until he meets his best friend sister.
