War leaves no one untouched. The horrors of the Great War are not the only ghosts that haunt Helen Morrow and her late husband's somewhat reclusive cousin, Paul. Unquiet spirits from another time and another conflict touch them. A coded diary gives them clues to the mysterious disappearance of Paul's great-grandmother in 1812, and the desperate voice of a young woman reaches out to them from the pages. Together Helen and Paul must search for answers, not only for the old mystery, but also the circumstances surrounding the death of Helen's husband at Passchandaele in 1917. As the mysteries entwine, their relationship is bound by the search for truth, in the present and the past.
