Books that I have read (I'll keep updating this list when I find other helpful books):
Coping Successfully with Chronic Illness by Neville Shone: Quite short but full of real encouragement. Also good advice on breathing and relaxation. Similar to anti cancer below, it's written by someone with personal experience of the issues.
anti cancer; a new way of life by Dr David Servan-Schreiber: WOW - Everyone should read this. Really helpful study of the science behind really helpful nutritional advice. Second half of book deals with your state of mind and how that helps your healing too.
The Emperor of All Maladies by Siddhartha Mukherjee: Fascinating history of cancer treatment, helps to understand the various treatments being offered, how & why they work. I really enjoyed reading it, even though some passages were a bit emotional.
The Cancer Whisperer by Sophie Sabbage: As I read this, after it being recommended by lots of people, I kept thinking "this is not me". She writes about taking control of your own treatment in ways in which I am not prepared to do. However I did get one good thing from the book. At one point she talks about the importance of being clear what your own personal goals are. For her this was to live ass long as possible, I realised that for me this is not the priority - for me my priority is to be pain free. Having realised this I have turned a corner in my coping strategies - so thank you Sophie.
Pain is really strange by Steve Haines & Sophie Standing: A short, beautifully illustrated detailed explanation of pain and how it works. I found understanding my pain really helpful in learning to deal with it.
Quiet The Mind &
The Little Book of Resilience both by Matthew Johnstone: These little illustrated books are very handy guides, really helpful starting points in helping me to feel better.
Cancer made me a shallower person: a memoir in comics by Miriam Engelberg: Very lighthearted, but touched on some familiar feelings - really lifted my spirits and allowed me to laugh.
Food Rules by Michael Pollan: A fun little guide containing such gems as "It's not food if it arrived through the window of your car" and "break the rules once in a while".
Coping with the Psychological Effects of Cancer by prof. Robert Bor et al: This one I found both too specialised and too general. Too specialised in that the language used was a bit inaccessible and too technical. Too general because it only covered some general psychological effects and failed entirely to mention some of the issues I have been having.
