A series of 5 books by author Stephen R Lawhead called the Pendragon Cycle. It's a Christian twist on the Arthurian legend. The first book is titled Taliesin. All 5 are available on Audible.
Have you tried the Warlord Chronicles trilogy by Bernard Cornwell? A pagan twist on the Arthurian legend. Or the Camulod Chronicles by Jack Whyte which is a Roman twist on the Arthurian legend.
As for audio books, wish I could because I'm an avid reader, but listening to someone else read will put me right to sleep.
I haven't tried them, but I will certainly give them consideration.
