Cam Jansen: the Birthday Mystery #20

No mystery is too great for super-sleuth Cam Jansen and her amazing photographic memory!

Mysteries follow super-sleuth Cam Jansen everywhere she goes...even to a party. Cam has put together a surprise party for her parents. But when Granny and Gramps call from the airport to say they have been robbed, Cam and her parents rush to their side. Now it's up to Cam to find the thief! 

The Cam Jansen books are perfect for young readers who are making the transition to chapter books, and Cam is a spunky young heroine whom readers have loved for over two decades.
