No Greater Love by Danielle Steel

On the maiden voyage of the greatest ship ever built, the Titanic, Edwina Winfield was returning from her engagement trip to England with fiance, her parents and five siblings. In one fatal, unforgettable night, Edwina instantly becomes a woman mourning the loss of the man she loved, and mother to her five brothers and sisters. Her struggles to keep the family together go on for twelve long years, but as each child sets sail at last, to Hollywood, Europe, and elsewhere, Edwina finds her own life finally, and frees herself from the ghosts of those she loved and lost on the Titanic. In this magnificent work that brings a new authenticity and immediacy to the Titanic disaster and its impact on those survived, Danielle Steel is at the height of her enormous talent as one of the world's most respected and beloved writers.
