Miss Morgan's Book Brigade by Janet Skeslien Charles

In 1918, Jessie Carson leaves her job as a children's librarian at the New York Public Library to work for the American Committee for Devastated France (CARD) in an area that was decimated by the Germans in the war. The philanthropist Anne Morgan created the group, which consists entirely of women. The village that Jessie is based in, Blerancourt, is largely destroyed-- the people living there are shellshocked and fighting to survive. Jessie and the rest of the Cards find themselves bonding with the residents and each other. In an alternating storyline set in 1987, aspiring writer Wendy Peterson works in the Remembrance Department at NYPL and stumbles upon articles about the CARDs and vows to make their work, all but forgotten, better known. Miss Morgan's Book Brigade is a sure bet for readers who enjoyed Skelsien Charles' book The Paris Library  or Lauren Willig's Band of Sisters.
