Karen's Book was not very good. It's just like an ordinary BSLS book. And since it's #100, you would think they'd do a little something extra, like for BSC #100. For that one, there was a big and important plot, and they made a big deal out of it. This book has very short chapters on some of the highlights of Karen's life. Not enough detail. They didn't even give a pragraph on Karen's parents' divorce! It's an okay book, but I wouldn't buy it. Borrow it from a friend, or the library.
