This is good, with the caveat that this is indeed a YA book. The idea and plot are interesting, but the invisibility aspect doesn't seem to impact the story much at all. And speaking of the invisibility aspect, the subtext and reasoning for it are about as subtle as a slap to the face. It's immediately obvious why it's happening to our main character, and I could have sworn that about twenty pages in she mentioned that she understood, too. But she obviously didn't, and it's painfully tedious to keep reading about her not understanding it. I'm also not a big fan of the ending. The message was meant to be about the disparity of living situations and opportunities between rich and not-rich people (I think?). But as the characters flaunt this during their parading around at the end, it was alas nepotism baby that actually saved the day. If there were more internal reflections for our main character, and if she actually thought for more than two seconds about something, I think she would have made a fantastic main character, and if the ending was better, this could have been a way better book.
