Kate and Paul Hanlon are settling in to life in the pastorate of Faith Briar Church in Copper Mill, Tennessee, but Kate soon finds herself knee deep in another mystery. Upon paying a condolence call to a grieving widow, Patricia Harris, Kate learns a long-buried secret. Patricia had given birth to twins when she was seventeen, and one of the children was given up for adoption. Now, the daughter she kept is in desperate need of a bone marrow transplant, and with no matching donors the only hope is to find the girl's twin sister. With a life on the line, Kate desperately searches for the missing twin before it is too late.
