The Smoke Ring (State Series #3) » (Unabridged, 7 Cassettes)

In the free-fall environment of the Smoke Ring, the descendants of the crew of the Discipline no longer remembered their Earth roots — or the existence of Sharls Davis Kendy, the computer-program despot of the ship. Until Kendy initiated contact once more.

Fourteen years later, only Jeffer, the Citizens Tree Scientist, knew that Kendy was still watching — and waiting. Then the Citizens Tree people rescued a family of loggers and learned for the first time of the Admiralty, a large society living in free fall amid the floating debris called the Clump. And it was likely that the Admiralty had maintained, intact, Discipline's original computer library.

Exploration was a temptation neither Jeffer nor Kendy could resist, and neither Citizens Tree nor Sharls Davis Kendy would ever be the same again...

Publishers Weekly

The setting of Niven's 1984 novel The Integral Trees was striking and imaginative, even for this acclaimed world builder; it's well worth the second visit made in this sequel. Around a neutron star an envelope of gas holds a breathable atmosphere and a strange profusion of plant and animal life, all floating in free-fall. Five hundred years after the crew of the Earth ship Discipline mutinied and deserted to this paradise, their descendants are still watched over by the ship's unbalanced computer mind. The machine is busy manipulating its one small contact group into exploring the larger city they have been avoiding for years. Aspects of this society are intriguingfor instance, the disdain of the better-adapted taller, thinner people for the ``dwarfish'' throwbacks, even though only the short can fit into the scientific relics of the old ship. As usual with Niven, character and story are just an excuse for working out the properties of his wonderful imaginary world, where people can fly like birds and ponds full of fish hang in midair. Unfortunately, in this book he fails to marshal the visual and dramatic flair needed to show it off to best effect. (May 1)
