Just finished reading that saga a week ago all i can say is wow best fiction saga i have ever read.
I am currently reading 3 books right now, first one is Shock Troops By Tim Cook its part 2 of 1 about canadians fighting in the great war and looks more at the fighting skills of the canadians from 1916/17-1918.
The second book i am reading is called A Most Dangerous Book by Christopher B Krebs, this one is about the roman historian Tacitus and his writeing of Germania and how it relates to the nazis self image of themselves......(this one is a bit more dry compared to the other 2).
The third one is Legends of the Samurai by Hiroaki Sato, and talks more about the orgins of the samurai and other specific details in terms of the way of the warrior.... (I have a hard time remembering the names of the people that are listed in this book because i dont know how to pronounce it properly, but at least i will have practice by the time i am done reading it).
