A Whisper of War — Shelley Sykes

During a chat with ghost friend Corporal Jared Scott, Casey brings up an idea that Philip, Zach, and Chucky think is ridiculous: women fighting in the Civil War! But Jared tells them he knows just such a woman, and now Casey wants to meet her. Casey gets her wish, but afterwards she feels led to help Althea get the answers she needs to rest in peace. Casey's quest for those answers takes her to books and through email to a historical society. What she finds not only helps Althea, it teaches Casey what the boys have already learned. The road to the past always begins in the present.
