Favourite Book

I have many books, over 300 at the last count, but my favourite one has to be Don McCullins 'Unreasonable Behaviour'; so much so that this is the 3rd copy I've owned as the others have fallen apart!
Don McCullin is my all time favourite photographer and his role as a 'war photographer' (he doesn't really like that title) is one I would, circumstances being different, I would have loved to have done.
