I really liked reading what she had to say about her alleged visitations from the souls in purgatory. I myself believe it, but that’s just me. I did not see anything in her private revelation or testimony that was contrary to the faith and morals of the Church. Still, it is an officially unapproved private revelation.
I read Nicky Eltz’s book and also Sister Emmanuel’s interview with her. Bot are good, in my opinion. I myself would recommend them.
