I’m am part way through reading the Xeelee Omnibus, and very much enjoying it. In the first book, Raft, I noticed that he used the word Mote on three separate occasions. I took the first as a homage to Olaf Stapledon Larry Niven but when it popped up again it really stood out, more so the third time.
I’m now on to Timelike Infinty and again the word has popped up.
That is 4 times in 234 pages - about 1 every 60 pages or so which does seem to be a lot.
E: crediting wrong author for Mote in God’s Eye
