Best Natural Birthing book?

I'm 30 weeks today and I'm honestly nervous and anxious about labor (I'm not the only one) I had a spinal fusion 17 yrs ago and the anesthesiologist explained to me that I cannot get an epidural OR a spinal tap so my only birthing options are natural with IV drip or be put under anesthesia while they do the c-section. I prefer to be awake when my baby comes into this world so I don't want the c-section option. Is there any natural birthing books that cover techniques on how to get through labor? I'm trying to prepare ( light workouts, red raspberry tea) for what's to come
