This book, for me, is a bit of a mess. My first encounter with Dan Simmons was through "The Terror", a phenomenal horror story that was recommended to me here on Goodreads, and I absolutely adored it. The style, atmosphere, and characters in "The Terror" combined to create one amazing horror experience. However, "Carrion Comfort" did not have the same effect on me.
"Carrion Comfort" is about a group of beings that have the power to control people and make them do anything. They can also feed off the life force of those affected. It's sort of a unique take on the vampire concept, where the victims are turned into Thralls. The premise is very good, and the book starts off really strong. But I found that around a third of the way through, it began to lose its way.
The characters didn't seem to be consistent. For example, Melanie undergoes a massive character change from being opposed to what she was doing to now being evil in her use of the power. The amazing horror slasher scene that occurs early in the book is brilliant, but future scenes seem a little forced and just not interesting. Maybe it's just that the first scene was so unexpected that it made all future "horror" seem dull in comparison.
I also found this book a hard read due to the derogatory comments about everyone. It didn't make it a pleasant reading experience. Plus, a lot of horrific things happen, such as forced incest and child murder, which are just shocking.
Overall, the book just became too ordinary for me and wasn't to my taste. Nevertheless, Dan Simmons is still a great writer.
