im a piers anthony fan and these books won’t necessarily help with pop culture but he is very prolific and I feel he has some stand out work. First his geooddysey series to me is his best work but likely not recognized as so. The incarnations of immortality I would take second but is likely more generally viewed as his best and I would agree it was before geoodyseey, kirilian quest is really neat along with many of his other earlier series. His most prolific and possibly well known is xanth. One thing is over time its leaned into its main thing which is puns and is very light hearted and fanciful. If you read from the start its a bit more serious but I think he did not intend to go beyond a trilogy. Its like ti was a trilogy and then a trilogy of trilogies and now the series number in the 40’s or something. I have not read them all. Another stand out is split infinity which is both fantasy and scifi. In short geodessey is a story or realy series of stories across time. incarnations is a world where magic is just another force of nature and magic and technology grew up together, kirilian quest is an intergalactic story where the speed of light cannot be exceeded by physical means, I think I explained xanth enough already.
