Consider Phlebas (Culture)
Finally back to science fiction, this brainy work is an interesting introduction to the Culture series. Originally piqued by the SpaceX naming of their recovery barges after characters in this series, I’m interested to see how it develops. While I enjoy the vivid imagery of this first book, I wasn’t particularly in step with the characters or their motivations. Still, it was an interesting read and I’ve been told the series only gets better.
