ILIUM

Hugo and Stoker winner Simmons (Hyperion) makes a spectacular return to large-scale space opera in this elegant monster of a novel. Many centuries in the future, Earth's small, more or less human population lives an enjoyable, if drone-like existence. Elsewhere, on some alternate Earth, or perhaps it's the distant past, the battle for Troy is in its ninth year. Oddly, its combatants, Hector, Achilles and the rest, seem to be following a script, speaking their lines exactly as Homer reported them in The Iliad. The Gods, who live on Olympus Mons on the planet Mars, may be post-humans, or aliens, or, well, Gods; it isn't entirely clear. Thomas Hockenberry, a late-20th-century professor of the classics from De Pauw University in Indiana, has, along with other scholars from his era, apparently been resurrected by the Gods. His job is to take notes on the war and compare its progress to Homer's tale, noting even the smallest deviations. Meanwhile, the "moravecs," a civilization of diverse, partially organic AIs clustered on the moons of Jupiter, have been disturbed by the quantum activity they've registered from the inner solar system and have sent an expedition to Mars to investigate. It will come as no surprise to the author's fans that the expedition's members include specialists in Shakespeare and Proust. Beautifully written, chock full of literary references, grand scenery and fascinating characters, this book represents Simmons at his best. (July 22)

Forecast:An 11-city author tour, plus the anticipation over Simmons's first new SF epic in years, will fuel sales. The conclusion to this two-part saga, Olympos, is due in 2004.
