[edit] Setting
The book is set on the planet Tenebra, a world with thick atmosphere, a shifting crust, crushingly-strong gravity and surface temperatures of over 370 degrees Fahrenheit. Human scientists have spent the last two decades studying Tenebra's intelligent life from the safety of an orbtiting laboratory.
[edit] Plot summary
The Tenebrans are intelligent, but primitive by human standards. Yet scientists from Earth have found ways to train and educate some of the Tenebrans. This training becomes crucial when two beings—a young girl from Earth and the son of an alien diplomat—are marooned in a bathyscape that is headed toward the surface of the planet, where neither can hope to survive.
