Unbroken tells the true story of Louis Zamperini, an Olympic athlete turned World War II bombardier. Hillenbrand has called Zamp’s life “almost incomprehensibly dramatic,” and she masterfully unfurls his story, which begins with his plane failing and crashing into the Pacific during a routine search mission. (After you finish, pick up Hillenbrand’s previous biography Seabiscuit, which is about so much more than a racehorse.)
