I had found that the novels after the tenth weren't that great, but this installment was awesome. The story line wasn't too complicated, and I loved the ending. I'm really looking forward to reading the 18th book. What I find really interesting is the big differences between the first books and the ones that are out now. In the first few ones, cell phones weren't big deals - neither was checking email - and now Stephanie has a cell phone, laptop, and her hamster is surprisingly still alive. That thing has got to be over ten years old. That's ancient for a hamster!
