Anything by Dan Simmons. "Hyperion" and "Fall of Hyperion" are literary, I am rereading soon, for the 4th-5th time.
Gregory Benford "Great Sky River" has several sequels.
Charles Stross is the best new author of the last 5 years.
William Gibson -- "Neuromancer" in 1984 created cyberpunk. Some of the sequels to that were weak, his last 3 novels are totally back in his prime.
Bruce Sterling. Lucius Shepard. Greg Egan. Alexander Jablokov.
Jack McDevitt -- astro-archeology. John Barnes.
Every year, I buy "The Year's Best Science Ficton", edited by Gardner Dozois, currently in its 27th year. That's where you spot the up-and-comers.
