Charles R. Morris "embedded" himself with a surgical team at New York-Presbyterian Hospital, one of the world's top cardiac surgery and transplant centres. Given unprecedented access, Morris witnessed sophisticated operations and observed the tense meetings where surgeons relentlessly criticise their own performance. In thrilling detail, Morris recounts a late-night against-the-clock "harvest run" to secure a precious transplantable organ; the heart-breaking story of a child's failed transplant; a trainee surgeon's brutal daily regimen and much more. Along the way, Morris documents the fifty years of research and hundreds of millions of dollars that have been spent on creating a reliable mechanical heart, and he steps back to reflect on how doctors think and how they judge each other. A brilliant business historian, Morris discusses what is really driving American health care costs and the future of health care policy in America.
