While the author of this account acknowledges that there are significant chunks of information missing about Joey Guerrero’s life, this biography nonetheless feels satisfyingly complete. As a young woman living in her native Philippines, Guerrero contracted Hansen’s disease (then known as leprosy) just prior to the arrival of World War II in the Pacific. Despite scientific knowledge that Hansen’s disease is not easily spread, and that 95 percent of people are immune, it was highly stigmatized; Guerrero received intermittent treatment in secret. Extraordinarily selfless and courageous, she worked with guerilla groups, passing critical information, spying, and, most notably, delivering—on foot—a map of land mines that allowed the U.S. military to liberate prisoners of war at Santo Tomas. After the war, Guerrero spent some time in a quarantine center where conditions were horrific; there she did all she could to improve the lives of other patients before she was finally given permission to travel to the United States for treatment at the renowned leprosarium in Carville, Louisiana. Largely considered a hero in both the United States and the Philippines for her service during the war, Guerrero chose to live a life of anonymity after she had recovered. While Guerrero is the primary subject, the compelling and compassionate narrative is supplemented by additional information about key events and people in the Philippines during World War II.
