Dienaj,
It's not really a "reading" book as such, more a work of reference with introductory chapters about the Command and its history at different stages of the war. However, you can look at a certain date and see all BC activity for that night: targets raided, effectiveness, losses etc.
For a good read, I would unhesitatingly recommend the books by Middlebrook on the Nuremberg (a disaster) and Peenemunde (a success) raids. He was a young lad living in Lincolnshire during the war, and used to watch the lads setting out on their raids.
