Warning to all fans of the series!
To those of you who loved the first three Mysterious Benedict Society books, be warned! Don't expect a fast-paced high adventure. The plot of discovering a long lost treasure is dragged out to the very end, and then--well, isn't quite so satisfying. Of course the "slowness" could have had a point: brilliant young Benedict holding back on discovering the answers because of his inner fears. So, maybe if I wasn't expecting a thrilling page-turning experience like the others, I would have found this book more satisfying. As it is, I am very disappointed to say I found it a slow slightly frustrating read. BUT give it a chance. With what you know now, you may be able to enjoy it more than I did.
(However, I absolutely LOVE the first 3 books!!!! Would recommend them to anyone!).
