Childbirth books?

I’m looking for a good facts-based birthing book.

All of the ones I’ve seen appear to be very biased towards natural births, which is what I want ideally, but I refuse to feel shame if I do decide to go with medication during labor or need a c-section and I don’t need a book making me scared about those possibilities.

I just want a book that will give me details about the stages of labor, what to expect, maybe some pain management tips.

Any recommendations?
