Pinging cynwoody for suggesting that may be the case at Post 294 on this thread.
It had long been rumored that something was going on between Petraeus and Broadwell. Her book, co-written with Vernon Loeb, is widely regarded as a valentine to the general. When she was embedded with him in Afghanistan, they went on frequent 5-mile runs together. But Petraeus went on 5-mile runs with many reporters, and few people who knew him took the rumors seriously. In his personal life, he’s always been seen as a straight shooter, a square. Few could have imagined that his end would come as the result of a morals scandal.
According to the Amazon writeup on her book:
Paula Broadwell has more than a decade of military service and nearly two decades of work in counterterrorism and counterinsurgency. She is a PhD candidate at the University of London. Broadwell received an MPA degree from Harvard. She graduated with honors from the United States Military Academy. She lives with her husband and their two children in North Carolina.
