Another Cullen~Twilight

What if there was another Cullen?
Who had been changed after Edward?
and she had some unique gifts?
what if the Twilight story was rewritten from her point of view?

Rowan Cullen was changed after Edward.
No one knows who changed her, but Edward found her one night, on an evening walk.
She was only 14 when changed, and Edward, Emmet and Jasper are extremely overprotective of her.
you see she was only half changed, she got gifts, and would never grow, like all the other vampires, but she can still be injured and get sick like human.....
