Robert Silverberg 
Dying Inside [EPUB ebook] 

Born with the extraordinary power to look deep within the human heart, David Selig recklessly misuses his gift in the pursuit of pleasure, until his power begins to die and he must come to terms with what it means to be truly human. This is a fascinating portrait. Never has the experience of telepathy been conveyed so vividly, so excitingly, so chillingly. And never has Silverberg created so moving a story, as he depicts the flux of dying and thrust towards rebirth.
