Query: Good First Sci-fi Novel

Reynold's Revelation Space was an interesting story on the way humanity began to evole into a different species through the use of science, though his claim that culture not nature as a vehicle for evolution was unconvincing.What I did enjoy was the scope of the plot of his novel that remind me of Isaac Asimnov's "The Foundation Trilogy" or Robert Blumetti's "Ironstorm." The galactic scope of the story was well done and believible soaring across time and space. If you like to read complex stories then I recormend Revelation Space.
