Casting Off — Elizabeth Jane Howard

The Cazalet family saga continues as they struggle to adapt to a new world after WWII in this international-bestselling series for fans of Downton Abbey.

The war is over, but for the Cazalets -- and England -- the challenges continue. Against the backdrop of a crumbling empire, the family soldiers on in the wake of disappointment, heartbreak, and tragedy.
 
Returning home after five long years, Rupert Cazalet struggles to adapt to civilian life back in England. And his wife, Zoe, harbors a guilty secret. Young wife and mother Louise Cazalet, trapped in a loveless marriage to a famous portrait painter, searches for a way out. Cazalet cousins Polly and Clary must face life in a new world, their hopes and ideals changed forever by the ravages of war. And Rachel's self-sacrificing nature could cost her her relationship with Margot Sidney. But the family comes together again as three generations of Cazalets struggle to hold onto Home Place, the beloved Sussex estate that has been their refuge and their heart.
 
Against the titanic sweep of history, as they are tested by infidelities, divorce, unimaginable loss, and the promise of renewed love, the Cazalets try to cast off the sins and sorrows of the past and sail bravely toward the future.
