This is the last of a four volume set, and I'm nearly finished with it. They are all incredibly good. Perhaps the best books I've read in my life, and I've read roughly 25 books on Buddhism, Christianity, new age scientific, and spiritual subjects over the last 3-4 years. I've never read a four volume set of anything in my life.
In general each of her books is better than the previous, presumably because she is becoming a better "channel", but I wouldn't skip the earlier books. Each book has a more refined and subtly conveyed message than the previous. The final volume holds to this pattern.
Its a very improbable story, her story. However, her personel story is only ancillary. Regardless of whether you believe her assertion of the source, the eloquence of the prose and the spiritual message are incredibly powerful. To make a point, not intending to denigrate Patricia's previous proffession in any way, I will say, "you will eventually come to realize that it would be impossible for a medical transcriptionist in Boise to write these books." I don't believe I have ever sensed a deeper commitment to unwavering compassion towards all sentient beings in any book, except perhaps the Dalia Lama's.
