I am so frustrated with this book. Mild rant ahead.

The writing is clunky, simple, withholding. I feel zero tension or fear, and don't even believe the characters are afraid either. The structure is such that we don't really get to see much of the character's personalities other than from the other person, a spouse who kinda hates the other right now-- so it's super fun to read snark and annoyance and constant bickering. The structure is also written to constantly edge the reader with ~cliff-hanger moments: 'but she didn't know what he had planned' 'only one of us would be leaving here' etc. But without there (yet) being any payoff, I'm not rushing toward a cliff edge, but like I'm arduously climbing a huge hill, getting more tired and convinced the view at the top will actually be total shit. I feel like the characters are dumb af-- if there's snow everywhere so why do they not notice a speck of it being tracked in, nor any footprints outside? There's constant little plotholes, like the power has been cut and the generator turned off but that freezer is still going? I'm not a fan of a thriller that dribbles out the information to the reader so things only make sense once the author finally gives you the information-- esp as we are in first person POV for the two main characters! We are in their heads and yet they aren't thinking about their plans or about the issues between the couple, so the reader doesn't know what any plans are so there's no real reason to care IF there is nefarious plotting because of UNKNOWN reasons... ugh
