Adult Protective Services (APS) is the social service system charged with aiding older people and disabled adults who are being mistreated by others or cannot meet their own basic needs for health and safety (self-neglect). These are America's most vulnerable citizens, and they often suffer for years, while remaining largely invisible to the greater world.

Written from the inside of APS, Mark Mehler's memoir of his seven years as a crisis case manager reveals a world that very few people see, and addresses why and how people do this work, what they take away from it and the price that they pay to do it.

Ranging from horrifying to uplifting and bizarrely funny, the stories recounted here witness human frailty and disaster, and the efforts of some dedicated caseworkers to stem that tide.
