Birthing from Within is an excellent choice. I would also recommend Hypnobirthing. And I second taking prenatal yoga classes or hypnobirthing class. Although the hypnobirthing encourages partners, it isn't necessary. I was going to take a class without my husband because he didn't buy into it.
Not sure if you don't want a partner, doula, etc or are just expecting not to have one at your birth. Many hospitals have volunteer doulas that are free and that you can request and there are women going through the training of midwifery or being a doula that would work for you for free or for a nominal fee.
Here's to your peaceful birth. I wish you well on your journey.
