The Forgotten Samurai Of The Sengoku Period [EPUB ebook] 
Honor and Betrayal in the Age of the Warring States of Japan

Let me set the stage. This is Japan, 16th century. It was an age of power, ambition and, yes, a great deal of chaos. The Sengoku period — when everybody was out fighting, plotting and backstabbing for that piece of the pie.
