Blood and Blood is a satirical collection of ridiculous musings, poetry, and prose, from the perspective of Genghis Khan as he conquered most of the known world and did lots of terrible stuff. He didn't actually write this book or anything like it.
...or did he?
The book is divided into four chapters, and each chapter serves a different purpose. Deals with a different murder. Stabs a different heart. This book takes readers through a journey of the most terrible moments in his life and finds more terror in them, because there are terrible things everywhere if you are willing to be terrible.
