I must preface this by saying that Dan Simmons is my favorite author. I have absolutely loved every novel I've read of his, and liked most of his short stories as well. However, this novel presented a challenge for me.
The first chapter was brilliant. In fact, it was originally one of his better short stories. But from there, the story plodded on at a slow pace, moving from one implausible scenario to the next. There were also some WTF asides from a secondary character who was yet to be fully understood.
Towards the middle, the pace started to pick up, and the rhythm of the story drew me in. But then, towards the end, some truly disturbing scenes took place. I usually avoid spoilers like the plague, but I have to say that one such scene was the most fucked up thing I've ever read. It felt completely unnecessary and out of place.
This really bothered me, and I don't understand why such a brilliant writer would make such a serious misstep. The ending of the book, while it didn't tie everything together in the neat bow that I'm used to with Simmons's work, did conclude satisfactorily.
Overall, despite the implausible twists and turns in the story, they were still entertaining. That, along with the ending, is enough for me to give this book three stars. However, I must say that this story in any other author's hands would have been simply unbearable.
I don't ever plan to read this one again, but I will have to keep it as it is a signed copy. I don't recommend this book unless you are a die-hard Simmons fan. To anyone else, I highly recommend Hyperion, which is my favorite novel.
