Shogun - Clavell James

Shogun is one of those rare books that you wish would go on forever. Indeed, I know people who re-read it every year. The story follows the adventures of marooned English sailor John Blackthorne in late medieval Japan during the tumultuous years when Tokugawa Ieyasu (here called Toranaga) was uniting all of Japan under his rule by any means necessary. It's truly an epic tale of war, honor, trechery, masterful manipulations, tragic heroism, and star-crossed love.
