Family history has always been a mystery to Will Latymer. His father flatly refused to talk about it, and with no other relatives to consult, it seems that a mystery it shall always remain. Until of course, Will meets Ghislaine, his beautiful French cousin, in a chance encounter that introduces him to his grandmother, Madeleine, shut away in a quiet Breton manor with her memories and secrets.

Before long, Will has been plunged headlong into the life of Madeleine's great love, his longlost grandfather, Henry Latymer. Reading Henry's old letters and diaries for the first time, Will discovers an idealistic young man, full of hopes and optimism - an optimism that will gradually be crushed as the realities of life under the Vichy regime become glaringly clear.

But the more Will delves into Madeleine and Henry's past, and into France's troubled history, the darker the secrets he discovers become, and the more he has cause to wonder if sometimes, the past should remain buried.
