Read the excerpt from "Surrendering” by Ocean Vuong.

Through the headset, a robust male voice surged forth, emptying into my body. The man’s inflections made me think of waves on a sea. Between his sentences, a crowd—I imagined thousands—roared and applauded. I imagined their heads shifting in an endless flow. His voice must possess the power of a moon, I thought, something beyond my grasp, my little life.
