The premise is this: just weeks before the planet Deepsix will be destroyed by a collision with a gas giant, ruins are detected on its surface, suggesting the presence of civilization. The Academy diverts scientists from the nearest spaceship to go down and explore, and they are joined by their century's Ellsworth Toohey: a misogynistic, sanctimonious gadfly who has never before been off of Earth's surface. The party's landers are destroyed in an earthquake induced by the approaching gas giant, so now they must find a way to get off of Deepsix before it is destroyed by the collision. Needless to say, their excavations are placed on the back burner.
The physics describing the space travel and the archeology used to reconstruct the lost culture of Deepsix are interesting and explained well. There is plenty of action and suspense--will the party survive? And the evolving characters and group dynamics are more complex than those usually found in science fiction books, making Deepsix a worthwhile read. --Diana Gitig
