Of the 1.3 million active-duty service members in the US military, only a tiny fraction are selected as “operators.” Shannon Kent was one of the first women to serve at this level and was widely recognized as one of the best. Shannon served as a Navy cryptologic technician, responsible for signals intelligence and electronic warfare, but her proficiency with language set her apart.

In Robert E. Lee, the award-winning historian Allen Guelzo has written the definitive biography of the general, following him from his refined upbringing in Virginia high society, to his long career in the U.S. Army, his agonized decision to side with Virginia when it seceded from the Union, and his leadership during the Civil War. Above all, Guelzo captures Robert E. Lee in all his complexity--his hypocrisy and courage, his outward calm and inner turmoil, his honor and his disloyalty.
