The first one I read some months ago. I don't recommend reading numerous books in between. Admittedly, I somewhat forgot some aspects from the first book that took a little while to come back to me, and were mildly important. With that said, I thought the dialogue in the first book was fantastic, and was lacking in this second version. This sequel seemed more concerned with action, which is okay, considering most people get bored with too much dialogue. But still, what the first lacked, the second had, and what the second had, the first lacked. Maybe third time's the charm??
Either way, it's a wonderful story for children and I had a fun time reading it. Children's stories should not be overly literary. They should be fun. This is certainly fun, and I look forward to the next in the series.
