The Years of Rice and Salt (Mass Market Paperback)

Some highlights from the alternate history: (Contains some spoilers for early sections) about 1400, a mutated and incredibly potent version of the black plague wipes out most of Europe, eliminating it as a political or military force. Christianity is eliminated as a civilization, and the later events are dominated by Chense and Islamic culture. Muslims, some of them refugees from mainstream Islam, gradually repopulate Europe. Meanwhile, a Ming expedition, outfitted to invade Japan, gets caught in a strong Eastern current, misses Japan entirely, and winds up in San Francisco Bay. The expedition is still very much a success, especially when it travels South and discovers the rich mines of Peru. A later Chinese fleet succeeds in conquering Japan.

A group of reformist Muslims, chased by more traditional sects, sails west from Normandy and discovers Manhattan. The Iriquois federation, becoming aware of the presence of alien cultures on both the West and East coasts, forms the North American tribes into a great union, capable of keeping the outsiders largely restricted to the coasts and holding the interior of the continent.

There is more, covering alternate histories of the Industrial Revolution, WWI, and the dicovery of fission, up to an age that look like roughly the present, with increasing global cooperation and, presumably, an alternate Francis Fukuyama to announce the End of Alternate History.

At key events in this timeline, we meet repeatedly the same group of people, recognized by keeping the same initials. The key figures are:

B - A spiritual seeker, frequently a Buddhist clergyman.
I - A scientist or intellectual, fascinated with acquiring knowledge.
K - The activist of the group, at first seeking revenge, at other times power, and ultimately social transformation.

All of these are followed through various lives and deaths, meeting up repeatedly in the Bardo, the between life area of judgment from Tibetan Buddhism. There are some minor accompanying characters, such as S, which is generally a feckless or irresponsible person, often of considerable authority, but these are the main ones.

Robinson has created numerous striking characters from these broad templates: a soldier in Tamerlane's army who ultimately becomes a slave in China, a protective tiger, a servant boy caught in the floods of a Chinese California, a young woman growing up in post-war Islamic France, and many more. It's really a virtuoso trick to fit 600 years of alternate history into one book while still having real characters to live the history, something Robinson has accomplished superbly.
