When I Sign the Rock by Aurora G. Rain

Life is all fun and games in Stanstead- until the Socialist war grows dire, and John leaves his best friend, Bethany, to go fight for his country.
Bethany is outraged at John’s rash decision, and can barely bring herself to see him off when he gets deployed. Soon, Bethany watches as the boat pulls away, taking her friend into uncertain lands. The only communication between friends is a series of letters. But when John stops writing to Bethany, she begins to lose hope.
Months later, she receives a letter- John has gone missing in action.
Bethany’s life begins to crumble as no other news arrives of the missing soldier. Her heart constantly questions the loss of her friend and her feelings. Is John more than a friend? And will he ever come back to her?
