I actually read the hardback version which was ordered from America but I can't find a link to review it.
There is an author's note at the end of the book which explains that "her grandfather was a slave", in other words as a four year old (white) child he was sold to a mid-Western tobacco farmer in America for fifteen dollars. This was apparently common in the hard times after the American Civil War. He ran away at 16 and never recovered from his bitter experiences: and this passed down the generations: Four of his seven children,including the author's father, committed suicide. Theory of War is a book of fiction but is an attempt to recreate what his life might have been like, and how impossible it was to escape the rage and trauma of such a life. It's a totally brilliant book the like of which I have never read before. If only the title were different, with its potential to put off readers who might misunderstand the content of the book.
