Ilium

The Trojan War rages at the foot of Olympos Mons on Mars -- observed and influenced from on high by Zeus and his immortal family -- and twenty-first-century professor Thomas Hockenberry is there to play a role in the insidious private wars of vengeful gods and goddesses. On Earth, a small band of the few remaining humans pursues a lost past and devastating truth -- as four sentient machines depart from Jovian space to investigate, perhaps terminate, the potentially catastrophic emissions emanating from a mountaintop miles above the terraformed surface of the Red Planet.

Dan Simmons is the Hugo Award-winning author of Hyperion and The Fall of Hyperion, and their sequels, Endymion and The Rise of Endymion. He has written the critically acclaimed suspense novels Darwin's Blade and The Crook Factory, as well as other highly respected works, including Summer of Night and its sequel A Winter Haunting, Song of Kali, Carrion Comfort, and Worlds Enough & Time. Simmons makes his home in Colorado.

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.

The author of the popular and highly praised Hyperion books returns to sf in his usual manner, applying a variety of raw materials to a very large canvas with a free hand. There is the cast of the Trojan War--warriors, women, gods, and all. There is a terraformed Mars. There are robotic scholars resurrected from literature, a pastoral but poisoned Earth (genetic engineering was overdone), and Savi, the Wandering Jew. The action in and around Troy is the easiest to follow, provided one is familiar with the Iliad. The action on Earth and the terraformed Mars develops more slowly because of the vast changes in human beings and the widespread development of artificial intelligence, which tends to follow its own rules, which Simmons must elucidate. Fortunately, Savi serves as a bridge between the past and the future. The book concludes with a cliffhanger, to be resolved in the forthcoming Olympos. Simmons has entered the ranks of those writers--a distinguished company, beginning with Euripides--who are disgusted by the gods' behavior in the Iliad. Broadly literate sf fans with a high tolerance for uneven pacing will be the readers who are best able to orient themselves. An impressive if not transparently accessible novel, and as such no surprise coming from Simmons.
