As with the other Magic Tree House books, I loved this one. Lots of adventure and cool ways to learn about Africa.
I love how Annie's inclusiveness and Jack's researching skills work together in the book. In this books, Jack and Annie work on their third riddle in order to become Master Librarians. I really like this plot and think it adds new depth to the series instead of just having Jack and Annie wander around in books.
I also love how Osborne uses fan suggestions in her writing. These books really feel like they are written for the reader.
A great quick read. I can't wait to continue Jack and Annie's adventures.
