When children are taken from their family, due to abuse or neglect, they enter the custody of social services and are put into a foster home. Some of these children are lucky enough to be given a Court Appointed Special Advocate (CASA). "One Child at a Time: The Mission of a Court Appointed Special Advocate (CASA)" shares the experiences of CASAs working to give children a voice in court, and a chance to return to a safe home, or to find a new forever home. First, you will meet Kelly, an engaging three-year-old that told her CASA the first time they met, "The people came and took me away from my mommy and daddy. I was crying and crying. I had to go and see a doctor. The doctor gave me a stuffed animal to make me feel better, but it didn't help." The words of this small child floored the author. She seemed to have a better understanding of her feelings than many children much older. It's no wonder that the author would become Kelly's biggest advocate. The second section of the book is a compilation of experiences and feelings from a variety of CASA volunteers. All kinds of people do this work; the only requirement is a love for children. Volunteers are trained for two weeks before starting a case. Along the way, when questions or concerns arise, each volunteer has a supervisor from the CASA office that they can turn to for advice and a listening ear. The joy of seeing a child find the happiness and security each one deserves is an experience that fills a CASA's heart with their own joy and happiness. It is the reason CASAs become hooked from the moment they take a case and meet their children.
