Dark Matter (by Blake Crouch, not "A Dark Matter" by Peter Straub that GP mentioned) was really terrible. Not only is the "physics" complete nonsense, the plot doesn't make any sense even if you accept his version of how physics works. Even if you suspend your disbelief and accept how the device works, the last 30 or so pages just completely ignore that and the final goal makes no sense at all. The scientists have cringey dialogue that sounds like it's straight out of a campy Hollywood action flick. The whole thing is driven by the cliche that you can either be successful and completely lonely, or have a family and be boring and unsuccessful. It's really quite bad.
