This past weekend I finished reading this long awaited (by me) novel. Clarke had been working on it for a few years but was unable to complete it before his death due to ill health. He passed it on to another one of my favourite authors, Frederik Pohl, to complete.
I won't go into a full review because doing so would spoil the novel. I'll just say it was a very good read and has all the usual Clarkian elements. Much of it is set in Clarke's adopted home country of Sri Lanka.
My impression was that it was an Arthur C. Clarke story but was written in the style of Frederik Pohl's novels. The characters were perhaps more developed than in most of Clarke's books; that may have also been Pohl's doing.
Happily, Clarke was at least able to see the final manuscript before he passed away earlier this year.
All in all, highly recommended.
It is currently selling for about $20 on amazon.ca so order it now before the Canadian price goes up, or better yet borrow it from you local library like I did.
