It will be very difficult to write this review without spoilers. However, I will try my best. I thought The Book of M was a science fiction book, however I would consider it fantasy instead. There is so much unbelievable in the story that I would believe in vampires before I would believe in the plot of The Book is M.

The premis of the novel is that people suddenly started loosing their shadows. Without shadows people could not remember. It turns out that memories are stored in our shadows and not in our brain. Without memories people started to drift away and humanity became its worse version of itself, except for the few who did not. After about a year most people were gone, either dead or shadowless.

The writing was excellent. It was engaging with strong identifiable characters. The plot was well thought out and, for the most part, flowed well. I was hooked from the start of the book. Everything about this book screams masterpiece, except the concept. The idea that memories are connected to shadow, that without shadows people can do magic, and that our shadows is the essence of ourself is hard to swallow. It goes against basic science. A shadow is where an object blocks light. No explanation was ever given for why or even how it started. It did not allow me to suspend my belief of reality.

The novel became more fantastical as the story progressed. I wanted to enjoy it all. The book was perfect on so many levels. It was just too much. The ending was a complex look at human nature. While it was not the mysterious twist that it tried to be, it was very character oriented. I enjoyed seeing how the characters reacted to the various situations. Except the event itself was hard to swallow.

The Book of M is one of those books that is amazing, but not for everyone. I am glad that I read it, but at the same time cannot help rewriting the story in my head so that all belief in science does not have to be suspended.
