I highly recommend James Clavell's Asian saga if you want to just buy six books and be good for a year. Also helps to keep a piece of paper and a pen handy if you have trouble remembering the characters and their different relationships.
Christ. That does not sound fun to me. Is the rough ridin' story any good? Samauri's graphically killing dudes and stuff?
Just trying to figure out the valuee add, here.
It's just a warning to dumbasses who can't remember crap. The stories are excellent and usually have between 40-70 characters with 10-15 main characters in each. The six books take place from feudal Japan through the mid-20th Century and, with the exception of two, revolve around a British trading company and its interactions in Asia (mainly Japan).
The real problem is that some ancestors of the minor characters pop up in later books so unless you have a really good memory you miss the connections. Not relevant to any of the stories, just an added bonus.
Clavell also wrote the screenplay for "The Great Escape" FWIW.
