The world has been taken over by organizations that pretend to be religious but are really political. Grant Archer is a Believer, but not a Zealot or part of the New Morality. He's married and ready to work on his astrophysical thesis on the moon colonies when an upper member of the New Morality sends him to Station Gold that's orbiting Jupiter to spy on the staff.
He was very upset when he got there, but finds out that they have a secret mission -- a ship went into Jupiter's ocean earlier and saw creatures that looked intelligent, but they had to come back with damaged crew -- and the second mission is getting ready to go.
At the last minute, Grant is put on the mission and they do find intelligent creatures that communicate with colored images on their sides. The crew were dying in the ocean and one of the mammoths put the spaceship on its back and lifted it up. Grant was able to run the thrusters just long enough to get into space where mission control could bring them in to Gold.
He has the other conscious crew member send a message that contains every bit of data they found so far out that it got to every human in the system. This angered his New Morality guy, whose ship was approaching the station, and a compromise is reached -- Grant will continue the Jovian studies, but won't have any communcation -- and breached with another staff member sending Grant's communications to his wife.
Bova quotes, without noting it's a quote, "Every Breath You Take" from Police.
This one is going to the library tomorrow -- I expect none of the bookgroup will want it so it will go to the Friends of the Library to sell.
