Sea of Death I finished, though it has issues - but - Leda-Eclavdra was every teen's fantasy. . I also managed to get through world-trashing Dance of Demons, which was pretty bad in places, terrible "buy my new setting!" finale, but ok for adolescent reading. Years later Upper_Krust sent me the one before DoD - Come Endless Darkness - but I couldn't get through it.So ... I remember (back when they were published) reading Saga of the Old City. And it was .... fine. I mean, Gygax wasn't a great novelist, but I like it, at the time.
And Artifact (I think?) was next. I vaguely recall it being ... not as good. I almost didn't finish it.
And after that, I think I tried to read the next one after he left TSR. And I wanted it to be good. Because GORD! GYGAX! SEA OF DUST!
It was terrible. I couldn't finish it. I really tried.
On the bright side, IMO the Gord books are way better than his Egyptian detective books!
