I didn't enjoy this book as much as I had hoped. I enjoyed Dark Matter a lot more. I didn't enjoy the two simultaneous story lines. It got confusing at time. Recursion is definitely not a light read. Blake Crouch likes to keep the reader thinking and guessing.

This book reminds me of something Stephen King would write.

It took me a few chapters to get into it, but I did I could not put it down. Great read. A little dark.
