Uplift series

I'm currently working my way through Stephen Baxter's Manifold trilogy. His writing is incredibly insightful and psychedelic. I'd also suggest the Time Ships (only authorized Time Machine sequel) and anything from the Xeelee universe. Maybe start with Vacuum Diagrams? David Brin's Uplift series is brilliantly written, and personifies non-human characters wonderfully. Heinlein has been a favorite of mine since I was a kid, and his writing always makes me giddy.

Some which I have re-read recently and still enjoyed: William Gibson's Sprawl trilogy Frank Herbert's Dune series Isaac Asimov's Foundation series Frederik Pohl's "Gateway" Robert Heinlein's "The Moon is a harsh Mistress" Some which I remember liking when I read them many years ago as a teenager: E.E. Doc Smith's Lensman series David Brin's Uplift series Peter F. Hamilton's Greg Mandel trilogy and The Night's Dawn trilogy Orson Scott Card's "Ender's Game" George R. Dickson's "Dorsai!"
