6 12 Years a Slave.
This book is the true story of what happened to a free black man from New York State who was kidnapped and sold into slavery in the South. The book is written by Solomon Northrup, the man it happened to.
I read this because the film has had such fantastic reviews that I really want to see it, but I much prefer to read the book first and then see the film than the other way around. It spoils my enjoyment of the book if I know what is going to happen, somehow this doesn't seem to matter as much with a film.
Also, in one of the reviews that I listened to, the reviewer couldn't believe that the events shown in the film could have been quite that bad and so read the book to see if they had exaggerated, to find that, if anything, the film tones it down. This made me want to know the full and accurate version of events before seeing Steve McQueen's take on it.
I was not as surprised by what was depicted as some of the film reviewers seem to have been, but it is still a shocking story. For me the full horror was not so much what happened to Solomon Northrup, dreadful as that was, but the fact that so many people where born into slavery, lived lives of suffering and degradation and died with no hope of release.
