Ilium is a remarkable yet imperfect work. I truly wish I could rate it as three-and-three-quarters stars. If you haven't delved into Homer's works recently, it would be advisable to do so before embarking on this book. I initially began reading Ilium but soon put it aside. I then read Homer's Iliad. After that, I returned to Dan Simmons' Ilium and completed it. I'm extremely glad I did. When Homer's epic is still vivid in your mind, you'll extract much more from Dan Simmons' book.
For my comprehensive thoughts on both Ilium and Olympos, which form a set, please refer to my review of Olympos.
Update: After spending three weeks thinking about the book and comparing it with other books I've read and ratings given this month, I've decided to upgrade the rating to a full five stars. Despite my initial misgivings about the beginning and not really being fond of the parts about the Greeks, the scope of this book is truly remarkable and it truly deserves the highest rating.
I did not enjoy the first 50 pages or so. I was confused and kept wondering what was going on. I even thought I would DNF (Did Not Finish) this book before reaching a hundred pages. However, the mention of "Mars" by the Moravecs caught my attention. They passed Mars's orbit and there was nothing to see as Mars was on the opposite side of the sun. A day later, they passed Earth's orbit and again, there was nothing to see as Earth was far around the curve of its orbit on the plane of the ecliptic far below.
The humans in the story eventually grew on me as well. But a third of the way into the novel, I still did not like the parts taking place during the Trojan War. They felt unnecessary, overly detailed, and rather boring. Greek mythology has never been my favorite. Nevertheless, even in this aspect, Hockenberry finally managed to win me over.
This book features great world building and excellent ideas. It is very dense and not suitable for a casual read. Overall, it is a good book. I might read the next book, Olympos, eventually, although I'm a little scared it might not be as good.
About 30 years ago, I stepped into the fascinating world of Greek mythology. But not in the Iliad and the Odyssey, but in two little books called The Legends of Olympus - The Gods and The Heroes, adapted by Alexandru Mitru from the works of Homer. I was then deeply impressed by all the characters in that fairytale world, who were superheroes in the eyes of my child.
So it was a great pleasure to discover, much later, Dan Simmons' novel, Ilion. A novel that I lived, not read, on both readings. For where else does it happen that Zeus, Achilles, Hector, Aphrodite and Odysseus from the Iliad/Odyssey sit, shoulder to shoulder, next to Prospero and Caliban from The Tempest by the most famous English author? Where has it ever been mentioned that two robots with consciousness debate the writings of Shakespeare and Proust? A novel in which the Trojan War takes new and unexpected directions, in which the Mycenaean and Trojan warriors from the Bronze Age meet the technology of quantum physics. Where the Greek gods are not exactly what I knew. And at the same time, the few inhabitants of a future Earth lead an idyllic and carefree life, impoverished of literature, art or music, and with a forgotten past.
All these narrative threads, which slowly approach a point where they will meet, prove the incredible imagination of Dan Simmons. Ilion is a superb and surprising novel.
