Or can he? Prot knows facts about space that are confounding the experts. He is soon revealing Dr. Brewer's own deepest pains and most sublime longings. And his tales of K-PAX have other patients competing to go along with him when he heads "home".

Published in a dozens countries with movie rights sold to the producer of Field of Dreams, K-PAX has touched the hearts and expanded the horizons of readers around the world.
