This has been on by TBR pile for years, and I finally made myself sit down and get through it. The reviews at Amazon and elsewhere are ecstatic, but I found it very slow going, full of purposelessly florid writing.
It's frustrating not to like a book that you should like. There are some neat things, as the book's protagonists encounter a world that a cyborg race is gutting with a cosmic string for a large-scale engineering project. Our main hero finds himself in the midst of an undergraduate physics problem as he gets dropped through a hole cut all the way through the planet.
But I kept finding myself not caring very much what happened either to the humans or the cyborgs.
