In Paris in 1975, Camille's mother has recently died and she is struggling to cope, when she receives the first of a series of long confessional letters from a man called Louis, recalling a love story set in the 1930s and 1940s. The Second World War and the German occupation of France are a backdrop to the story rather than a main part of it.
Louis loved Annie from when they were at school together. Annie became friends with a wealthy woman who moved to their village. Madame M is desperate to have a baby and somehow persuades Annie to help her. A complicated, tragic story unfolds.
I enjoyed reading this novel and working out the story, but I didn't find most of the characters entirely convincing - Annie seems too good to be true, and Madame M too scheming and unpleasant. Various references to historical events of the time seem to add little to the story, which is not about the political history of the time.
With these reservations, this is still worth reading, and I would probably read another book by the author.
