William Cohen served as Secretary of Defense under President Bill Clinton from 1997–2001. He was a member of the US Senate and Congress for 24 years - representing Maine. He has written for The Washington Post, The New York Times, and The Wall Street Journal and is the author of The New York Times bestselling Dragon Fire.
Drawing from his years of dealing with international crisis and defense planning as well as his interest in NASA's continued research on asteroids, Cohen now creates a sweeping, all-too realistic political thriller entitled Collision.
