Dark Matter is a thriller science fiction novel by American writer Blake Crouch, first published in the United States in July 2016 by the Crown Publishing Group. The story is about a physicist who is kidnapped and sent to a parallel universe in which another version of his life unfolds because of a different choice he made fifteen years prior. The book draws on the many-worlds interpretation of quantum mechanics which posits that every possible outcome of every event creates a new universe or world that runs parallel to our own.

i watched the apple tv series before reading this book, and i think the tv series actually did a better job with building suspense. there's not much to say about this novel; it's a typical time travel mystery.
