I'd waited a long time for the concluding book in the excellent Time Odyssey trilogy, and wasn't disappointed by it. True to form, Clarke and Baxter's latest collabaration delivers. If sci-fantasy is your thing, this may not be for you, but for fans of pure science-fiction, there is much to make you think. In terms of style, I would say most of the writing is Baxter, but the plot is definitely ACC's broad visionary style. I would say that it is almost essential to have read the previous 2 books in the trilogy first in order to fully appreciate the detail and subtleties. Even though it is the last book in the trilogy, some details and questions remain when you get to the last page, scope for another book? I hope so. In summary, there is much here for the discerning sf reader, an excellent story backed up by good scientific thinking.
