The Call of Nursing takes us behind the scenes of a profession that hides in plain sight and offers twenty-three intimate self-portraits of women and men on the front lines of health care.  Practicing in the U.S. and abroad, the nurses featured here capture the full sweep of the profession. Their stories offer a glimpse into the ordinary heroics often invisible to the public eye while underescoring a compelling call to practice and a deep personal motivation to help people in need.
