August 1914. England is at war. As Evie Elliott watches her brother, Will, and his best friend, Thomas Harding, depart for the front, she believes--as everyone does--that it will be over by Christmas, when the trio plan to celebrate the holiday among the romantic cafes of Paris.

Christmas 1968. With failing health, Thomas returns to Paris--a cherished packet of letters in hand--determined to lay to rest the ghosts of his past. But one final letter is waiting for him...
