Caesar, who's he?

About this book

"Having saved Cleopatra once before, the children of the Nile are faced with yet another plot to thwart. This time, pirates are threatening Alexandria, the capital of ancient Egypt. The three children may be brave, but they're only ten years old ... So when they hear talk of a certain Roman general named Caesar, they know who to go to for help!"--P. [4] of cover.
