The inspiring memoir of a young doctor and former college athlete who became a champion for people suffering from rare, under-researched diseases--all while battling his own. A former Georgetown quarterback nicknamed "The Beast," David Fajgenbaum was also a force in medical school, where he was known for his unmatched mental stamina. But things changed dramatically when he began suffering from inexplicable fatigue. In a matter of weeks, his organs were failing and he was read his last rites. Doctors were baffled over a condition they had yet to even diagnose; floating in and out of consciousness, Fajgenbaum prayed for the equivalent of game day overtime: a second chance.
