Dear Casey,
I don't know who Lucille is, but I like Byron's simple, straight-to-the-point approach. I believe self-inquiry, self-realization, and turnaround will prove to be helpful. I also think univestigated stories unnecessarily and repeatedly fester old wounds. So, I guess "The Katie" book is time-worthy.
If you don't mind me asking, "What do you coach?"
Ciao,
Brose
