Awwww.. that's so sad! I felt so sorry for Mattie.
I sank to the floor, burying my face in my hands one more. This couldn’t be happening. Just yesterday I had been telling Lucas what to do if these people came up to him. But now that advice seemed do useless, even my life seemed useless. I stumbled outside and sat down on a chair and looked up at the sky. I wondered, as clouds went across the sky, how they could keep going, when so many things were happening to the world, all the pain and suffering, and some of that pain was happening to me. The pain felt so real that I could run a thousand miles, or scream at someone, at the world. And yet, as I thought of the millions of other people that were suffering in the world, I felt so small, that I should just sit down and cry, because that’s all I could do, so insignificant against the world.
This bit is so descriptive. It was really beautiful. I also liked how you made Henry the comforter. Their sibling relationship is so sweet.
