When the Australian pilot is sent back to the front, Emily volunteers as a "land girl," tending to the neglected grounds of a large Devonshire estate. It's here that Emily discovers the long-forgotten journals of a medicine woman who devoted her life to her herbal garden. The journals inspire Emily, and in the wake of devastating news, they are her saving grace. Emily's lover has not only died a hero but has left her terrified--and with child. Since no one knows that Emily was never married, she adopts the charade of a war widow.
