I read this book with my children (10 and 6). Though I thought this was as interesting as the others, my children didn't find it as captivating. My 6-year-old actually thought it was boring when we were about half way through. They ended up liking it at the end. They still want to continue with this series. However, as this one didn't interest them as much as others in this series, they no longer seem as excited about it as they used to. As a whole, this series so far has been great. My children have loved most of them.
What do You think about The School Skeleton (2003)?
