Eddings’ problem was that he kept writing the same books and characters, over and over again.
For all that, the original five Belgariad books were a pretty good read. Even the sixth, Guardians of the West might be deemed enjoyable.
Books 7-10 were the original series, just re-written over again. He then went on to do the same thing with the other series he subsequently wrote (or so I heard - I think I read one-half of the first book in the Elenium and said “Enough: I’ve read this before!”).
For all that, the original Belgariad was pretty entertaining fantasy. I have no trouble recommending them to people - especially to relatively younger readers. Problem was - those five books were all that Eddings had to give. After that, he ended up just writing a pastiche of the Belgariad - time after time.
As for Piers…well. I read the Xanth series in the early 80s. Tarot, The Apprentie Adept, and a few other earlier series from the 60s and 70s which were far less “commercial” as I recall. In one story, I recall that he wrote some wierd alien sex scene where this species had sex by rotating a ball between them with their lower musculature. It was pretty odd.
At a younger age, Piers seemed entertaining enough and the first few Immortals series had their moments too.
Bio of a Space Tyrant in the mid-80s was my permanent parting of the ways with Piers Anthony. It wasn’t the sex thing at the end with the girl. That was tame and imo, depicting a sex scene with a sexually mature adolescent is a very different matter than depicting it with a pre-pubescent child. (At least - my recollection was the girl in Bio was 14 or 15 - something like that). Point is, one story is clearly pedophilia while the other is not. (Sorry to American posters but the world doesn’t necessarily share your squick factor on depicting teenaged sex as being “inherently wrong”).
No. What got to me was the simplistic Right-wing political allegory that runs throughout Bio of a Space Tyrant. It was so ham-fisted that I realized (I was about 19 or 20 at the time) that this author was intended for adolescents - not adults.
That was the end of me and Piers Anthony. Never read another book of his and never will.
Now - all this stuff about sex with ten year olds and six year olds is, admittedly, quite creepy.
