Keeping up with the multitude of characters from Greek mythology can be a handful. Illustrated with colorful digital artwork and accompanied by a map of ancient Greece, these entries in the Greek Mythology series give children a brief, age-appropriate overview of some of mythology's most interesting gods and goddesses. Ares explains the god's moody behavior and desire for battle and highlights the differences between him and his biggest rival, Athena, also a goddess of war. Other features include sidebars, which make connections to art, the constellations, and other areas of ancient Greek culture. Good background knowledge for the Percy Jackson series, too
