I disagree with Keelis' (review below) closing line, which by the way is absolutely superb: "Overall, this book may appeal to you if you like books which are very slow and boring." A killer put-down, but I think it's a little bit unfair on poor Bella Bathurst. OK, the book is definitely jam-packed with clichés about the horridness of being a teenager - but that's the whole point, teenagers ARE clichéd, and that doesn't make their suffering any less real... I definitely remember the years Bathurst describes as being pretty d-n awful, and I think she does a good job of keeping your attention throughout all this dreariness. Maybe it's a little bit voyeuristic, but it's still effective.
One quibble, though: girls like Cat always pop up in these sort of books: perfect Lolita-like little creatures, old beyond their years in their exquisite cruelty. I agree that girls (just like boys) can be real bullies, but I wonder if this not an idea we carry with us from adolescence... at that point, these sort of girls seemed to be the devil incarnate, when they were probably just as freaked out as we were. Or is that just me becoming old and well-meaning and totally out of touch??
