I can describe his Requiem for Homo Sapiens as…Philosophic Fiction? I read it about 10 years ago, and was instantly hooked - that trilogy is why I went into Philosophy.
It is …fantastic, although I wouldn’t call it fantasy in the sense of swords and sorcery, and it is futuristic, but I wouldn’t call it Sci-fi in the vein of Clarke Asimov, etc.
Anyone else read anything by Zindell? I started reading his actual fantasy series, but it falls massively short of Neverness and the Requiem trilogy.
