I read anything that's nailed down, or even just moving slowly. Cereal boxes, candy wrappers, all genres, etc., and I don't always have much time for arbitrary distinctions like literary fiction vs. genre fiction.
I started reading Tana French's books because I wanted to get a flavor for contemporary Irish life. I'm getting that, in spades, but I'm also getting first-rate mystery stories. In the Woods is maybe more melodramatic/action-oriented, whereas this one is more psychological, almost claustrophobic in places.
