This is part of the Canongate Myth Series, which has contemporary authors re-telling ancient myths.
I soaked up all the Greco-Roman mythology I could get as a kid. My parents cleverly gave me a gift-wrapped copy of D'Aulaires' Book of Greek Myths right before boarding a flight to Florida. That was an extremely effective way to keep an eight year old Jared quiet for three hours.
Despite an interest I've never immersed myself in other cultures' myths to the same degree. Having them actually presented as fiction like Byatt does here worked better than attempting to read about it as non-fiction. Previous non-fiction sources I've tried are either superficial or fractally labyrinthine. I think the framing story Byatt chose was a little superfluous though it does get points for lyricism.
Harriet Walter's narration in the audiobook version I listened to was quite good. There were several passages of extended lists of beasts and plants and such that worked much better narrated than it would have in print. What would have been skimmed over in print had a hypnotic quality when spoken. (See lyricism remark supra.)
As a whole it was certainly good enough for me to pick up other books in the series.
