I had to quit at 7 hours because the characters just got too annoying. The arguments were caused simply out of stubbornness from both sides and it was so exhausting. The cause of the car sliding out in the snow because she was freaking out and pulling on the steering wheel while he was refusing to take anyone's directions was such a cliched scene that I had to wonder if the author was secretly a guy or if she's simply a fan of dumb stereotypes
