"Shogun" is a book published in 1976 by the author James Clavell.

It is an epic about an English navigator who finds himself in 1600 Japan, and trying to adapt to a society alien to him, meanwhile helping the Lord Toranaga win his battle to become the ruler of Japan.

Adapting to a new environment is the least of his problems, as his ship and crew are confiscated, and he finds himself in the middle of a 3-way power struggle between the Lord Ishido, Lord Toranaga, and the Jesuit priests.

"Shogun" is one of my favorite books, as well as one of the most famous epics in the modern world.
