The opening sentence of My War Gone By, I Miss It So by Anthony Loyd:

There were places among the crowded trees where the birdsong dropped away to nothing, shaded clearings with a sound vacuum; once you had stepped in no noise could reach you from the outside world except the rustling summer breeze, and you did not want to listen to that too carefully, for if you were alone your mind began to play tricks and it was more than just the grass that you heard whispering.
