I've only read Conversations with God, Book 1. It was recommended to me by the non religious member of the spiritual staff at a rehab I went to in 2012 when I sought her out after hearing her lecture, after which I dubbed her Mystical Meredith. I've written about that meeting a few times, most recently and well detailed here: https://medium.com/illumination-curated/my-understanding-of-god-life-death-and-the-between-lives-we-experience-with-our-many-soulmates-af641080747f

As I gave my highly self annotated copy to a friend years ago and never got it back, I recently purchased another copy and will read it again.
