Q & R: Naked on audio?

Here’s the Q:

I hope you don’t mind me emailing this to your team but I am not sure where to look next! I love in the north of England in a lovely city called xx. I am just coming to the end of reading your excellent book ‘Naked Spirituality’, which was recommended to me by someone who thought that it might encourage me and give me a different perspective on things that I am finding rather frustrating about a life of faith. Indeed it is and I feel like I’m only scraping the surface.
Anyway, a relative is a lovely lady, who is ordained. She is great to chat to, particularly about matters of faith, and gets frustrated with simplistic answers to life’s challenges and likes to ask difficult questions of God, the Church and life. I saw her today and was telling her about your book, which I think she would love (particularly the ‘Perplexity’ section). However, she is unable to read well so I have been on an Internet mission to find the audio book.
However, so far I have had no success. None from a UK or US company that I can find.
Would you be so kind as to point me in the right direction or could I purchase one from you directly?

Here’s the R:
I wish I could explain why some books are converted into audio and others aren’t … but I really don’t know. For some reason, Naked Spirituality wasn’t. I’m hoping we can do something about that in the future … but for now, it’s only in print. I’m sorry! Your relative might enjoy my newest book, which is available in audio format.
