I think the biggest trouble I have with this book so far is that the characters are utterly insufferable. =( I find it hard to care about them despite the divisions the book makes.
Rich vs. poor.
Girl vs. girl (complete with slut shaming).
Twin vs. Twin/ Sister vs. Brother (their relationship is steadily growing apart, it seems, for life and interests.)
I'm trying to figure how the girls will end up falling in love with each other at this point, but I think I'll employ patience and go with it.
