I loved labour of Love by Gabrielle Targett also! I have just bought her hypnobirthing CD too because I was so impressed with her book. I also really like New Active Birth (J Balaskas) and What to Expect was/is my general guide. Also, the Incarnating Child is a lovely book too. Mind you, I never knew there was a recommended reading list on BB either, but I just liked the books that I mentioned.
Happy Reading
