Many years ago, "The Cosmic Computer" was one of my entry points into SF, and I decided to reread it for this review. And it is still pretty good! Deep psychological thriller this is not, it's a tech driven story with just enough human interaction to keep it interesting. The MC is a Heinlein like competent man with a mission and the start of a plan. What makes the story so interesting is the unfolding of the plan in a complex fully fleshed universe. The MC follows their path through it, illuminating fascinating snapshots of stuff going on away from the main story line. Don't expect a LeGuin ending but do expect to have a happy, warm buzz. (BTW, the author was more influenced by the Annales than Carlyle.)
