At the end of book 3, I thought I liked these books. They exceeded my expectation, and I had a wonderful time with them. However, the last book was suddenly terrible and destroyed every positive feeling I had ever had about the previous books. I could not finish it. The story progressed significantly slower than before, thus making the whole book boring. It took so much of my energy to finish a chapter. I finally decided that I had had enough. It was such a shame because I quite liked books 1-3. Anyway, the book cover is stunning, haha.
