Daniel Berrigan. Night flight to Hanoi. New York: Macmillan , 1968  

“Impacted, like many, by major events such as the Watts riots in Los Angeles, as well as the deaths of President John F. Kennedy and Dr. Martin Luther King, Jr., her work took a turn. Further liberated from any constraints when released from her vows, her work encompassed a more direct activist message. She created pieces about the deaths of Dr. King, President Kennedy and Senator Robert F. Kennedy, as well as works vehemently condemning the Vietnam War as morally abhorrent.”
