What is the poem the following quote is from? I can't seem to find the name. “I had never seen a person/so finished with God/her face was a massacre of grief/her cries like shoveled granite/chewed her shrilling throat“all that they left was the flag”she kept screaming/I thought her lungs would start bleeding/it scraped my chest clean/hollowed me for weeks/our house was the echo of a mother/clawing the floor boards for her dead son/a down forest in her nail beds”
