Greg Mortenson, the bestselling author of Three Cups of Tea, is a man who has built a global reputation as a selfless humanitarian and children’s crusader, and he’s been nominated for the Nobel Peace Prize. But, as Jon Krakauer demonstrates in this extensively researched and penetrating book, he is not all that he appears to be.

Based on wide-ranging interviews with former employees, board members, and others who have intimate knowledge of Mortenson and his charity, the Central Asia Institute, Three Cups of Deceit uncovers multiple layers of deception behind Mortenson’s public image. Was his crusade really inspired by a desire to repay the kindness of villagers who nursed him back to health when he became lost on his descent down K2? Was he abducted and held for eight days by the Taliban? Has his charity built all of the schools that he has claimed? This book is a passionately argued plea for the truth, and a tragic tale of good intentions gone very wrong.
