An evocative retelling of the story of Sister Vivian Bullwinkel, through the eyes of fifteen-year-old Edith 'Edie' Kenneison.

Sister Bullwinkel enlisted in the Australian Army Nurse Service at the outbreak of World War II and was posted to Singapore. In February 1942, she and hundreds of others attempted to escape the advancing Japanese army through Indonesia, but was captured and held as a prisoner of war on Bangka Island. Vivian spent the next three years in captivity, working tirelessly to help her fellow prisoners. One of those prisoners was young Edie. Their remarkable friendship would help them survive and became the basis of a lifelong bond.
