Dark Matter by Blake Crouch

A fast moving book about regret and missed opportunities–but in action, not reflection.

Jason Dessen is the hero of the story; a smart professor who has settled into a comfortable life with his family, teaching at a local college. Then it all goes sideways.

Jack was wise when he recommended it to me without much detail, just an enthusiastic recommendation to read it. I’ll say the same, mostly to avoid spoilers.
