After a not-so-helpful visit to a psychiatrist, Wren goes for a run in the middle of a cold winter night. She is found laying on some rocks not far from her house. She is starting to get hypothermia and has to be hospitalized. During this situation, the title of the book begins to make sense. Wren says,
"The woods are dark and deep, and I run through them until I can't feel anything anymore...I tear through deeper and deeper parts of the woods. Like if I'm fast enough, the forest might open up and let me in for real. I run until I'm burning. My lungs screaming in my chest, my muscles on fire. My heart's a machine" (Page 243).

Even though Wren's midnight run makes her seem like a lunatic, it opens her eyes. Her family's reaction to seeing her on the fringe of death makes her realize that she is loved. She sees that they really are on her side, wanting everything to be okay for her. She begins to take steps on the way to feeling happy and normal again.
