Yesterday, courtesy of Cloud Library, I finished Manifold: Time (1999), by Stephen Baxter. It’s my first exposure to Baxter, who has written 60 science fiction novels — none of which I’ve read. Per his Wiki bibliography, he’s written only a half-dozen short stories, also none of which I’ve read. (There are SF authors I’ve only met in short story collections. He isn’t one of them.)
Time is the first of the Manifold trilogy (which has a fourth book, Phase Space); the second and third books are Space (2000) and Origin (2001). Each of the books tells a separate story in a separate universe.
I enjoyed the first book, but I can’t say I was hugely whelmed.
