The true story of John Nash, the mathematical genius who was a legend by age thirty when he slipped into madness, and who--thanks to the selflessness of a beautiful woman and the loyalty of the mathematics community--emerged after decades of ghostlike existence to win a Nobel Prize and world acclaim. The inspiration for the Academy Award-winning movie, Sylvia Nasar's biography is a drama about the mystery of the human mind, triumph over incredible adversity, and the healing power of love.
