By the way, Kate, I meant to ask if you've come across Lorna Byrne's books on her experiences with angels? Marvellous combination of the ordinary and the extraordinary. (I first read about her via Jonathan Black's 'Secret History of the World'.) As a girl she was treated as retarded because she seemed to be away with the fairies, except, little did the muggles realise, she was actually away with the angels. Chatting with them. Getting them to help with vindictive teachers, for instance.
It took me a while to get into the books, but gradually the combination of extraordinary perception and everyday necessities (motherhood, bereavement, housewifery) convinced me this was special. Mysticism for the 21st century. No caves, stylites, monasteries or nunneries needed. But big insights if you're prepared to stick with her and see what comes up.
