Dark Matter by Blake Crouch could not have been more different than Nine Women, One Dress, my last book. I could barely put it down and kept updating my family at every turn about the next surprise the book held. It is very challenging to write about Dark Matter without spoiling it. Suffice it to say, Jason is living a normal life with his wife and son until one night when he is knocked unconscious. He wakes up to a life where his wife is not his wife and he has no son. In addition, his life is no longer ordinary: he is a celebrated genius who has invented something impossible. Is this a dream? How does he get back to the life he knew? The story twists and bends reality and keeps you on your toes at every step. And, while I am not sure I fully figured out how it all could possibly work, it was a good ride, nonetheless.
