Butterfly by Sonya Hartnett
Awkward, alienated, angry teenager Plum looks in the mirror, and hates what she sees. No one appreciates her - least of all herself. But when a beautiful, sophisticated neighbour invites Plum over, things change. Plum learns how to be different.
But the new Plum confuses people. Her friends treat her differently. Her brothers and parents don't know what to make of her. And for Plum and her new mentor, the transformation has unforeseen consequences that neither will ever forget . . .
