Reddit reviews A Brief History of the Celts: Brief Histories

I've found Peter Berresford Ellis is a good author to seek out for an introduction at least. He breaks the Celtic world down in very informative way that's easy to digest. He has a book called The Mammoth Book of Celtic Myths and Legends but it is not available in an audio format as far as I know. For me it has the best compilation of Celtic folklore, drawn from some of the most popular stories. There are sections where he addresses the history and culture of the various Celtic peoples, but the stories are largely all told via narrative. But again, no audiobook.

Another of his books, A Brief History of the Celts, does have an audio version. However, it's much more focused on history, culture and society. There's some mention of Celtic folklore but not presented in a narrative fashion.

I did a [quick search] (https://www.audible.com/search/ref=a_hp_tseft?advsearchKeywords=celtic%20mythology&filterby=field-keywords) on Audible and it gave me quite a few audiobooks on Celtic mythology and folklore, but I haven't listened to any of them so I can't speak to their quality.
