Shogun

Blackthorne, now a broken but wiser man, is offered a choice: he can return to England on a new ship, or stay in Japan as Toranaga’s permanent vassal (a hatamoto —a direct retainer). He chooses to stay, partly because he has nowhere else to go, but mostly because he has found his soul in Japan.

Japan is on the brink of civil war. The elderly (the former regent) is dead, leaving a child heir. A Council of Five Regents rules in his name, but the regents are deeply divided. The most powerful and ambitious is Lord Ishido Kazunari , who wants to become the next Shōgun (military dictator). The only regent strong enough to oppose him is Lord Yoshi Toranaga , a brilliant and cunning strategist.

But Ishido takes Mariko’s husband (Buntaro) hostage, and then demands that Mariko return to Osaka as a "hostage" to guarantee Toranaga’s good behavior. Toranaga reluctantly sends her, knowing she may be killed. Blackthorne, now a broken but wiser man, is

Ishido and the other three regents (backed by the Jesuits and the Portuguese) have formed a coalition to destroy Toranaga. They have declared him a rebel and are preparing to attack his lands. Toranaga is vastly outnumbered, trapped in his own castle, and running out of options.

**The Lessons of Honor and Ningen

Mariko’s death galvanizes Toranaga’s cause. It also breaks Blackthorne’s heart. He realizes he has fallen in love with her—a love that was impossible and never consummated, but that has made him a new man.
