Not necessarily books, but:

Pantheon/the stories it's based on by Ken Liu (though I really do recommend the animated series).

Maybe more conventional/dated, but I always recommend it for "getting" the emotional, person-to-person side in a particular way that few others do: .hack//SIGN. None of the characters ever quite realize what's going on, but elements - especially the soundtrack - seem to understand that everyone is on the precipice of something irrevocable.

  Shine, bright morning light
  Now in the air the spring is coming
  Sweet blowing wind
  Singing down the hills and valleys

  Keep your eyes on me
  Now we're on the edge of hell
  Dear my love, sweet morning light
  Wait for me, you've gone much farther, too far...
