Query: An unbelievable book!

I didn't expect to like this book but after the first few pages how could I not? It was fantastically written, one of the best books I've ever read. It was the kind of book that you don't want to end. The stories about friendship and love really sought out your emotions. It was hard to put down. Judy Blume is an excellent writer and I recommend this book highly. If you've ever fallen in love or ever had a best friend, than this book is for you.
