Marking Time — Elizabeth Jane Howard

For fans of Downton Abbey, the second volume of the critically acclaimed Cazalet saga takes readers into the lives of an extended British family and their devoted retinue
 
It is 1939, and Hitler has just invaded Poland. The exigencies of wartime will force the Cazalets to make difficult choices as the older children are evacuated from London and settled in Home Place, their longtime Sussex summer estate.
 
Narrated primarily through the voices of three Cazalet cousins -- sixteen-year-old Louise and fourteen-year-old Polly and Clary -- Marking Time details the continuing saga of their fathers. With the outbreak of war, Edward is determined to do his part for England. Hugh, crippled in World War I, must sit back and watch other men fight for their country, including his brother Rupert, who enlists and goes missing in action.
 
The Cazalets' story plays out against the greater drama unfolding on the world stage. Three young girls yearn for the freedom they believe adulthood will confer upon them in this tale of struggle and sacrifice, love and loss, as a new generation of Cazalets makes itself heard. With strong female characters such as the stoic Kitty; her daughter, Rachel, who's in a relationship with another woman; and the loyal governess Miss Milliment, Marking Time explores the role of women during the war amid early stirrings of feminism.
