At the library where I work, this book got massively popular (not only due to the movie) but as it is a Battle of the Books selection for the local elementary schools. The movie trailer looked so cute, and I kept hearing good things about it. I loved the short chapters of this book as it helped the pacing as the book explored multiple seasons on the island. In the back of the book, there were included sketches of the author's original idea of what Roz and Brightbill should look like, which are fun to compare to the movie's adaptation of Roz. However, when I started (and then ended) the book, I was unaware it was a series, and I was SHOOK and SAD to see it ended on a cliffhanger when I was fully under the impression that it was a standalone novel.
