The morality is good, but it should not be read to children who become scared easily.
Plot
When Dr. Cooper takes a break from investigating some temple ruins, one of his new and inexperienced assistants - against the advice of his elders - ventures down a shaft they know nothing about. A strange song known as the Song of Ha-Raphah is sung and a strange superstition goes along with it.

Lila rescues a goat. The Coopers search for a real explanation for Ha-Raphah instead of believing what everyone else says about him and look for logical explanations for this creature's power instead. Jay and Lila refuse to worship the false deity.
