K-Pax

Adapted into a major motion picture of the same name starring Kevin Spacey, Gene Brewer's K-PAX has touched the hearts and expanded the horizons of readers around the world—a thought-provoking masterpiece of modern-day fiction.
Psychiatrist Gene Brewer doesn't have a diagnosis for the mysterious new patient who calls himself "prot" (rhymes with goat). But this strange and likeable man cannot be—as he claims—from the planet K-PAX.
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". Now the doctor is racing the clock to find prot's true identity before he losses a man whose "madness" might just save them all. . .
