Query: A good period piece

This book nicely outlines the drama of human interaction against a rich background of relationships and changing times. The friendship between 2 near-adolescent girls is well-explored and quite realistic. The emotions and disillusionment of a very young Civil War soldier are well-expressed and may be applicable to current times. Familial relationships and ties are explored. Its ending will surprise you.
