I decided to relive my childhood with this book while reading something easy and enjoyable. And it was, it didn't suffer from the Princess Diaries problem of no time passing as this book covers a year and is much more like a diary. It was funny, was fairly close to how I experienced school and boys at that age and I read it in a couple days.
My only issue with the book is the rather problematic references to LBGT people which reflects the time is was written (1999) and unfortunately now. I'm not sure I'd let kids read it just because I don't think I'd want them thinking like that. But as an adult I can see the problem and know better.
