Through her travels around the country as an artist and activist, Mary Fisher encountered countless people locked in life-and-death struggles against AIDS – and the indomitable, memorable individuals who provided their care. To make visible this "invisible army of compassion," Mary Fisher set out to photograph caregivers of children, women and men with HIV and AIDS. She traveled from a nursery in West Palm Beach, Florida, to the women's prison on Riker's Island; from an AIDS clinic in Birmingham, Alabama, to a Michigan food bank preparing meals for AIDS shut-ins. Moving in close, Mary captured their compelling stories. Moving in close was often difficult, she wrote: "My cameras made me feel as if I were an intruder." The result: a moving album of stories that illuminate the courage, dedication and love of caregivers, the angels in our midst.
