Hey SJ - I have it, and have had it for a few weeks now and am a little more than half way through I should be finished by now but I don't know why but a few bits were a bit of a hard slog. I am coming up to massage, breathing and positioning so it could be that the anatomy/pelvic sections took me back to my uni days and hence the glazed stare!

Having said all that, the info in there is amazing and really useful for knowing your body, how to open it up more fully and I'm hoping in the next few sections, lots of practical things to take to labour.
It is excy but I think you will find you will easily make your money back if you decide to resell once you have finished with it!!
