Here's a book I narrated for recently, now on sale on Audible, The Babel Resurgence written by the lovely Jeffery Dale Cole, with whom it was a pleasure to work!
Something that Jeffery did for me very early on in the process, after contacting me through ACX was to send me an image of the actor that he saw playing each different character in The Babel Resurgence 'Movie'. It was an invaluable aid, so thanks Jeffery. It really helped me to conjure up the voices for the main characters before I embarked on the read and something that I have asked other authors to possibly think about doing when discussing how best to read their characters.
Although one chapter had to be re-read as I found out too late that a minor character I had voiced as a US accent was in fact German.
It's a good read and worth a listen, has a touch of christianity in it although I wouldn't put it down as a 'christian fiction' novel. I think it stands alone as a sci-fi story.
Check it out. https://adbl.co/2K4sojg
