Rebecca's Steve recommended Simone Weil to me the other day. (We were sitting in Ganley's Irish Bar. in Morden, a venue where the topic of Christian mystics can't help come up over a Guinness or two.)
I have found an In Our Time about her from nine years ago here. (Melvyn and guests are always worth listening to and there is a reading list as well.)
I can see that Awaiting God: A New Translation of Attente De Dieu and Lettre a Un Religieux by Simone Weil is available is an eight and a half hour unabridged audiobook narrated by: Rosemary Benson. I will probably add it to the library when my next Audible credit arrived on the 20th.
