Just finished this great Civil War fiction.  Tells the story of real life spy Elizabeth Van Lew.  A 43 yr old woman who lived with her widowed mother and was a member of the Richmond elite, Elizabeth was a staunch supporter of the Union and worked to see that union prisoners were given food and medicine beginning with the battle of Manassas in 1861 with men being thrown in the what is now known as libby prison.   While doing this she had the bravery and the opportunity to get information out and back to the forces in the north all the while keeping up the appearance of a loyal confederate.  She was considered the most effective Union spy.
The book was very well written and I enjoyed it very much
