Of course it's not really a novel- or rather, no more of a novel than Ulysses or the Waves- meaning it's about language more than it's about people or society or whatever.
It's one long authorial monologue; The characters speak in the same voice as the omniscient narrator and are placed at such a distance from us- as if viewed through a reversed telescope- that we hardly care for them.
And is the story gripping? Do we strain to know what happens next? No, of course we don't.
I have brushed the surface. This is a rich, thick, deep, clotted text. It invites study.
