I've read only Noble House. It's quite rich on the culture--maybe not so much as Shogun--and captures the setting quite well, but I didn't find it nearly as entrancing as Shogun.
Worth a read, still.
Likewise. Noble House was a good read, but Shogun was much better.
Clavell's whole Asian Saga (Shogun, Tai-Pan, Gai-Jin, King Rat, Noble House, and Whirlwind) is amazing. My favorite is Tai-Pan - the book had a tremendous impact on me, and I'd imagine it would appeal to every real entrepreneur. The underlying themes are freedom, individualism, honor, risk-taking, and ultimately, building something and defending it.
After Shogun I read a bunch of his books. The only one that stood out for me was Rat King.
> Rat King
It didn't stand out enough for you to get the title right though ;)
