A fantastic sci-fi epic in the tradition of Simmons's Hyperion Cantos. In Ilium, as in the Hyperion books, Simmons really shows off his knowledge of classical literature. He obviously knows the Iliad and the Odyssey inside and out, but the author (through his characters) also fills this book with literary and historical references to Shakespeare, Proust, and a dozen other sources. It's ingenious and it made me to resolve to finally get around to reading the Iliad myself once I've finished this series.
Set in the 40th century, Ilium is a retelling of the Iliad. Kind of. We begin with "scholic" Thomas Hockenberry, who was an early 21st century classics professor revived by the Olympian gods in the 40th century to monitor the ongoing Trojan War — which is taking place on Mars.
"Wait, what?" you are thinking. The "gods" are creatures of super-science, using unimaginable powers of quantum manipulation and nanotechnology to take on the roles and attributes of the classical Greek deities. And not just the big names either — while all the old familiar gods like Zeus and Athena and Aphrodite of course figure heavily into the plot, Simmons, through his educated protagonist Hockenberry, encounters scores of minor named gods and heroes as well.
Just why the gods are reenacting the Iliad on a terraformed Mars is not made clear by the end of this volume, but the heroes — Achilles, Hector, Paris, Odysseus, etc — are also as epic as the gods, thanks to both nanotech enhancements and literal interbreeding between gods and mortals, just like in the myths.
Hockenberry and his fellow scholics are basically embedded journalists for the gods, but although they all know how the Iliad ends, they have been forbidden by Zeus to tell any of the other gods. The gods know that the scholics know how Homer said the story is supposed to end, but they've been forbidden to ask the scholics. So they continue playing their games with mortal lives.
And then Hockenberry is recruited by one of the gods for a clandestine mission to kill another god. And with the "magic artifacts" he's been given, he's able to change a key event. And suddenly we're not in the Iliad anymore. And Hockenberry, who's now a dead man as soon as the gods catch up to him, decides to change the story completely.
This would be a pretty awesome story all by itself, but in fact Hockenberry is only one of three main protagonists. There are two other subplots which eventually merge into the Iliad on Mars. A pair of "Moravecs" — a race of sentient robots built by post-humans before they disappeared, now living out among the moons of Jupiter — is on a mission of their own. Not having paid much attention to the inner system for generations, they discovered a lot of dangerous quantum manipulation and advanced terraforming on Mars. When they go to investigate, their ship is shot down... in orbit, by a bearded man in a chariot throwing a lightning bolt at them.
Mahnmut and Orphu, the only two survivors, try to make it across Mars, aided by mysterious "Little Green Men" who seem to be creations of neither early humans nor the gods. The two robots, whose dialog is kind of reminiscent of R2D2 and C3PO, if C3PO were a Shakespeare scholar and R2D2 were fond of Proust, add a bit of comedy relief to the story, but eventually have a role to play in the climactic confrontation between gods and mortals.
Finally, there are the last surviving humans on Earth, a tiny population of laborless dilettantes with little to do but go to parties and play musical beds. Their world has been created by the long-gone post-humans, who created teleportation networks around the world, set up a system in which all remaining humans are carefully population-controlled and do not have to work or want for anything. They are granted perfect health until their "fifth twenty," when they report for exterminationascension to the outer rings, Logan's Run-style. But as Eloi-like as the remaining human race may be (they are actually called "Eloi" by one of the old-time humans they later meet), the spark of curiosity hasn't completely died in all of them. A few set off on an unplanned adventure, and discover truths about their world... and that there are Morlocks.
Ilium is so rich in world-building and has such a tangled plot that there were occasional bits that lost me — I am still not sure of the role of Caliban, the Little Green Men are just strange, and we don't yet have an answer to the question of why super-advanced godlike beings have resurrected the entire cast of the Iliad on a terraformed Mars. But hopefully those questions will be answered in the second book, which I will be reading soon.
