I bought the whole series for my daughter to read. We haven't gotten around to them yet, but we will soon. I've heard very good reviews for each of the books. I, too, was disappointed to see AG was discontinuing the series. Books 15 & 16, or maybe it is 14 & 15, are alread absent from the website and one of them I had to purchase from an out-of-print seller on amazon.com
