At the age of thirty-one, John Nash, mathematical genius, suffered a devastating breakdown and was diagnosed with schizophrenia. Yet after decades of leading a ghost-like existence, he was to re-emerge to win a Nobel Prize and world acclaim. The inspiration for a major motion picture directed by Ron Howard, Sylvia Nasar's award-winning biography is a drama about the mystery of the human mind, a triumph over incredible adversity, and the healing power of love.
