Gather the Bones — Alison Stuart

In the shadow of the Great War, grieving widow, Helen Morrow and her husband's cousin, the wounded and reclusive Paul, are haunted not only by the horrors of the trenches but ghosts from another time and another conflict. As the desperate voice of the young woman reaches out to them from the pages of a coded diary, Paul and Helen are bound together in their search for answers, not only to the old mystery but also the circumstances surrounding the death of Helen's husband at Passchandaele in 1917. As the two stories become entwined, Paul and Helen will not find peace until the mysteries are solved.
