Shōgun

Very much the Samurai oriented Game of Thrones that word of mouth sold it to be. I'd go an additional step further in specifying a more acute comparison to House of the Dragon, as Shogun leans more into the socio-political aspects of its feudal 16th century Japan. It's over 1000pg count allows the characters to breathe and develop through its various revelations, fights, betrayals, and romantic ties. While I would say that author James Clavell gets a little trigger happy with his assumption that seppuku was committed on the fly left and right, Clavell does take detailed pauses to showcase the stark cultural differences between the English, Portuguese, Spanish, and of course, Japanese. It's a tome to get through, but I did enjoy my time with it—possibly the longest I've taken to read a single book ever.
