I am really, really hoping she doesn't love Twilight.

I am going to horrifically honest: as a teen I think I would have loved this book with a passion. It really is aimed at pretty much everything my 14 year old self would have thought really, really important. I think I would still have rolled my eyes at the sparkling and the control freak behaviour but the rest of it I would have eaten up with a spoon.

But maybe your half-sister is a better and stronger person.
