Based on this comment, I think you will find Armstrong's path especially amazing. She went through a long period of feeling much as you do, after her convent years. She could not find God as it was taught to her by western Christianity, and only later and somewhat by accident discovered that perhaps there is something sacred, it is just different from what she was taught.

She also had some very interesting experiences with a medical condition that went undiagnosed for a very long time. The way she writes is so authentic and non-judgmental that I think just about anyone can appreciate what she has to say.
