Dark Matter by Blake Crouch is a thrilling sci-fi novel that revolves around the life of Jason Dessen, an everyday physics professor with a doting wife and a young son. After a night out with an old college friend, he finds himself being chloroformed and waking up in a new world, an alternate reality where his life is completely changed. He is no longer with his family—his wife is married to a rich and powerful man, and his son was never born—and he learns that he was abducted by a deranged particle physicist, who plans on using him as a guinea pig in his experiment to explore alternate realities.

Jason becomes desperate to get back to the life he had before, and soon finds himself on a dangerous journey through the various alternate universes that exist. Along the way, he learns about the “multiverse” and its implications for the fundamental laws of physics. He also encounters alternate versions of some of the people he knows, as well as a mysterious, enigmatic entity known as the Stranger.

As Jason and the Stranger travel through the various parallel universes, they are pursued by powerful forces who want to stop Jason and use him for their own purposes. In their quest to eventually return home, they discover secrets about time, gravity, and space that could shake the world and alter the fate of humanity. Ultimately, Jason’s odyssey forces him to rethink his understanding of the world, the universe, and himself.

Dark Matter is a gripping and imaginatively-wrought story, brought to vivid life by Blake Crouch’s evocative writing. It is a thought-provoking exploration of love and loss, family, identity, and the very fabric of reality. It is a thrilling ride that blurs the boundaries between science, fiction, and the metaphysical, leaving readers breathless and questioning their own perception of it all.
