I think reading the first book has that sense of newness that is found lacking in subsequent books. I felt it here, but at the same time I enjoyed the story, once I sorted out the book and movie thing The plot thickened and new people and aspects were brought in. Great way to continue a story and keep the reader interested.
If you liked the first book, I highly suggest you keep reading. Don’t watch the movie or the TV show first if you can help it.
Note: I purchased this book with my own funds with no expectation of a positive review.
