In the quiet hills of rural Kentucky, Mariam Caldwell loses her husband, her faith, and her voice—all in a single winter. When she discovers her late mother's handwritten psalms hidden inside an old hymnal, she embarks on a journey to retrace the life of a woman she never truly knew. Through dust-choked archives and long-buried family secrets, Mariam learns that her mother's prayers were laments, her hymns were confessions. As past and present intertwine, she must decide whether broken words can still become songs—and whether a heart shattered by grief can ever learn to sing again.
