In Book 2 of the “Kane Chronicles”, the Texas-based author of the “Tres Navarre” mysteries cleverly uses hilarious, romantic, magical, and thrill-packed entertainment to educate young adults about ancient Egyptian mythology. He’s very sneaky that way. But we’re not surprised since he did the same thing with Greek mythology in the “Percy Jackson and the Olympians” series. Ditto with Roman mythology in the “Heroes of Olympus” series. Face it, you’re going to need a roadmap to keep track of all the different ways Rick Riordan has brought the legends of ancient gods and heroes into the present day. But in spite of the globe-trotting complexity of the action in this book, and the relative unfamiliarity of the gods, monsters, and mythological concepts it introduces, this is a deceptively easy book to enjoy.
