When Marianne LePatourel meets William Ozanne in the 1830s on an island in the English Channel, she sets her heart on him. However, her sister Marguerite falls in love with him too. And so begins this sweeping novel that takes the characters on dramatic adventures from childhood through old age, on land and at sea, and from the Channel Islands to China to the New Zealand frontier.

When Williams naval career is cut short, he settles in New Zealand and writes to Mr. LePatourel to ask for Marguerites hand in marriage but in his nervousness he pens the wrong name. When Marianne arrives aboard the ship The Green Dolphin, William makes the gallant decision not to reveal his mistake. His mistake sets in motion a marriage that is difficult, but teaches them both that steadfast love which is chosen is stronger than the passion of love at first sight.

This historical drama is fiction but the letter writing mistake is based on fact. This novel was made into a 1947 film by the same name.
