“my lungs sucked at being lungs.”
“A fierce hand gripped my chest, squeezing my lungs. No. it wasn't my lungs. It was my heart. It was breaking.Wasn't I stronger than this?”
“Every third step I ran, my breath exploded out of me all in a rush. One step to suck in another cold lungful. One step to let it excape. One step of not breathing.”
“Might have punctured a lung, if he had a lung. Most trees don't, as a rule.”
“Keep your shit together," I whispered to my lungs.”
“I took a deep breath and filled my lungs with summer.”
