I am not really a non fiction reader. My Dad is, the most of his reading would be non fiction! The non fiction I read is professional reading - I am a teacher and so I always have a professional book on the go.
Other kinds of non fiction books that I read are How to.... books. If I want to learn something I in the past read this type of book. Not so much now, usually I can learn what I need by going online.
I do enjoy reading autobiographies and memoirs. Not that I read many of them but I will pick them up more when I have more reading time in my life. This year I intend reading:
Spanning the twentieth century, the magically vivid letters of the legendary Mitford sisters constitute not just a superb social and historical chronicle; they also provide an intimate portrait of the stormy but enduring relationships between six beautiful, gifted and radically different women who wrote to one another to confide, commiserate, tease, rage and gossip -- and above all, to amuse.
No Time For Romance is Lucilla Andrew's story, the powerful and moving account of a young girl in wartime London, learning the hard way about medicine, injuries and death, as well as love and hope. It is a story both of personal courage and of the courage of the British people at war.
I read many of her novels as I was growing up set in war time London and I loved them. It is probably her autobiography that I will read first.
