Max Brooks is the author of the bestselling novels World War Z and The Zombie Survival Guide. He is also a non-resident fellow at the Modern War Institute at West Point. His new graphic novel, Germ Warfare, details the brutal history of microscopic diseases used as weapons of war. Max and I talk about how why he wrote the book, his role as a consultant for national security panels, and how his mother, Anne Bancroft, instilled in him an awareness of disease and love of science at an early age.
