Don is a citizen of the Interplanetary Federation - yet no single planet can claim him as its own. His mother was born on Venus and his father on Earth, and Don himself was born on a spaceship in trajectory between planets. And he fights for the rights of this curious citizenship in very curious ways. Heinlein reveals in a dashing fast-moving style what can happen when politics - on an interplanetary scale - disregard the liberty of the individual. In the end, only the remarkable scientist-dragons of a rebellious Mars can resolve the conflict within a man who cannot live without the society that he knows is killing him.

This is the standard reference for over twenty years, now completely revised and updated with many new illustrations. "Gemstones of the World" is the most comprehensive and informative colour manual of the world's gemstones and includes more than 1,400 examples. Opposite each illustration the text provides an exact description of the particular stone, including details of the properties and chemical composition which makes the stone unique. Information on location of major deposits, alternative names, stones most easily identified incorrectly, and diagrams of their crystal habits are also given. The tables on gemstones' properties and constants provide a basic system of elimination for all unidentified stones. There are also eleven tables listing commercial and mineral names, refractive indices, dispersion, pleochroism, fluorescence, absorption spectra and specific gravities of gems. From the historical to the scientific, this extraordinary reference source is filled with fascinating facts about gemstones, both precious and semi-precious. It's also a worldwide scientific survey, with stunning colour photographs of each gem and its varieties.

After the fall of the American Ayatollahs as foretold in Stranger in a Strange Land and chronicled in Revolt in 2100, the United States of America at last fulfills the promise inherent in its first Revolution: for the first time in human history there is a nation with Liberty and Justice for All. No one may seize or harm the person or property of another, or invade his privacy, or force him to do his bidding. Americans are fiercely proud of their re-won liberties and the blood it cost them; nothing could make them forswear those truths they hold self-evident. Nothing except the promise of immortality…

Her first space trip - and not just to Venus but to Terra as well that most improbable of planets. It was a place where the natives had to go wrapped and protected against their own environment, a place where the gravity was too powerful for her species. Yet, according to one school of history, Terra was where humans like her had had their origins. But now the Mars shuttle was waiting to take her on her great adventure.
