It was definitely one of the saddest books in the series, but I loved it anyways. I love how creative Kathryn Lasky is with the names of the animals too. However, it may be a challenging book for younger readers, as the vocabulary is quite advanced. I first read it when I was in 4th grade and that was ok for me, but a challenging book means you learn more from it, right? Overall, it's an amazing book and definitely my favorite book of all time.
