Dark Matter is one of the fastest reads I've picked up in several years. People often say a book is "difficult to put down" or a "page-turner", but rarely do I find a book where I think that estimation is entirely deserved - this one fits the bill. Written with fairly short chapters, clipped sentences, plenty of dialogue, and lots of action, this book flies.
While I didn't particularly like the main character, and found much of the story predictable, ultimately it didn't reduce my enjoyment. The ideas were intriguing, and some of the places the story ends up were far more disturbing than I anticipated. There are a lot of existential questions raised (though not terribly elegantly - this book is heavy handed rather than subtle), and whenever I put it down I was left thinking. This book is a thriller, a sci-fi adventure, and a fast paced fun read, but it also has plenty of interesting things to say. All in all it was the perfect quick read to get me out of a reading slump. If you are looking for something that will keep you glued to the page, and will throw some fun thought experiments into the mix, you should give this book a try.
