This book documents the inspiring and cautionary true story of Bruce and John Klingbeil, a father and son team of devout Christian Scientists who dared to test their faith in the power of prayer, and of Spindrift, the research organization that helped to support their efforts.  The story describes the Klingbeils’ courage and personal commitment to learn the truth about the efficacy of prayer, their self-taught but ingenious experiments, the staggering hostility they attracted from both the religious and the scientific communities, and ultimately, the unbearable poignancy in their untimely and mysterious deaths.
