" My body rises with the water. Instead of kicking my feet to stay abreast of it, I push all the air from my lungs and sink to the bottom. The water muffles my ears. I feel its movement over my face. I think about snorting the water into my lungs so it kills me faster, but I can't bring myself to do it. I blow bubbles from my mouth.
Relax. I close my eyes. My lungs burn. "

― Veronica Roth , Divergent (Divergent, #1)
