Query: This is the most incredible book ever written.

I read this book for the first time in 1998, when I was fourteen, and I read the entire thing again in a month. I read a lot of books, but this one surpasses all others. Shogun is the most incredible, detailed book that exists. You are immersed in medival Japan, and never completely leave.
