Mysteries follow super-sleuth Cam Jansen everywhere she goes...even to a park with U.F.O.s in sight! Cam and Eric see flashing lights in the sky, and everyone thinks aliens have landed. But Cam knows there's more to it than meets the eye. Can she solve this unearthly mystery? 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.
