Dark Matter, by Blake Crouch - Book Review 

I recently read Dark Matter, by Blake Crouch, as part of a bookclub. And now that the TV show adaptation is coming out, I figured it'd be a good tone to post a review.
So here's my thoughts on this mind-bending, horrifying thriller.
No spoilers at first, then I move into light spoilers yo explain the sci-fi premise, and finally the last part is full-blown spoilers.
Enjoy!
