The Jesus incident

Frank Herbert

The last survivors of humanity have just been deposited on Pandora, a horrific, poisonous planet rife with deadly nerve-runners, hooded dashers, airborne jellyfish, and intelligent kelp. The determined colonists attempt to establish a bridgehead on the deadly, inhospitable planet, but more trouble arises. Their sentient ship - backed up by an impressive array of armaments - has decided it is God and is insisting the colonists find appropriate ways to worship it.

In an attempt to help the people pass its test, Ship awakens chaplain-psychiatrist Raja Flattery from hibernation. Either the humans pass the test - or the human race could be destroyed.
