A great addition to a wonderful series! This adventure includes Camicazi, Fishlegs, the Hairy Scary Librarian, and Driller dragons! Since David Tennet narrates this series, I will add this Dr Who quote "You want weapons? We're in a library! Books! The best weapons in the world! This room's the greatest arsenal we could have." Some other readers found this adventure less exciting than the previous ones. But I whole heartedly disagree. I loved every second of this book, it continued the fun world Cowell has created. And I always like a good tale about a library.
