SOLVED. A girl lived in the sky on some type of balloon homes, got around using ropes? [s]

I remember reading this book a while back and I remember really liking it, it was a young adult book. I don't remember much of the details from the book but I do remember that there were two main characters, a boy and a girl. I'm pretty sure the girl lived in the sky on hot air balloon type things and they got around from balloon to balloon using ropes. I feel like there was some type of underground fighting or something with robots. I'd love to read the book again and see if there were more than one book I just can't remember the name of it. Help!
