Rooftoppers is one of my favourite books (and titles) ever! Every time I look it up though, it tries to auto-correct it. xP Rather annoying, but I still love it so much!
Some of my favourites are:
Rooftoppers – novel
Echo – novel
Cartwheeling In Thunderstorms – novel
Dust – novel
Heaven’s Twin – novella (my own)
