With Ian Watson, weird is an insufficient word. Ditto for meta, and most other words. He likes to invent new ones and uses language like few others do, which helps to keep things fresh. But the amazing thing about him is how while pushing boundaries and going to new heights of seemingly randomness, there's still a methodical core of genius holding it together. But you can be forgiven for not catching it. It takes quite a bit to get through this short book with its density of character dialogue and its present tense, quasi-subjective narration. The subjects jump wildly as each crew member and Homer opine, pun or discuss subjects in a free-association sort of way a bit too much like real speech between people too smart for their own good. The subjects range from the future history of the world, actual history, biology, physics, philosophy, chickens and 20-21st century movie references almost like you're lost clicking links on a wikipedia page. It starts to come together over half way through in a way that made me feel brilliant for realizing that the narrative style itself plays right into the beginning of the story; almost an infinite tale, though it isn't and doesn't need to rely on that cheap trick. After all, it's a story about time travel featuring an alien causal-paradox that can only be solved by the accidental discovery of a supposedly impossible meta-dimensional hyper intelligence. I think.
Like other things I've read by Watson, it has lots to say about many things, and only he can somehow make it all seem to work together and 'natural'. If I had one wish from this book it would be only some more to like and grow on the characters individually. It was hard to concentrate with all the chattering riff-driven dialogue. The crew almost feels like a scifi collective-mind as they interacted with Homer, aliens and the Brain from Beyond. But certainly interesting and fun to revive me right when I was beginning to worry that I was growing bored of fiction.
