Marrying My Ex-Fiancé's Cousin

From the back cover

Isolde Vancrest believed she had found the right man in Alan Princeton, her fiancé of three years. Then she learns that Alan has gotten his widowed sister-in-law, Sandra Carter, pregnant, and that his family expects her to accept it. When Isolde protests, Alan's mother, Ruth Whitmore, strikes her and throws her out into the snow, barefoot and wearing only a thin sweater. Alan does nothing to stop it.

Alan insists his family needs an heir, since Isolde cannot bear children after an injury she suffered saving his life. He even suggests she raise Sandra's baby as her own. But Isolde remembers that Ruth once threatened suicide to prevent the marriage, so she and Alan were never legally wed. Free of him at last, she calls a man named Bruce, whose words from years ago she now means to collect on.

By morning, Isolde returns to the Princeton estate with a new marriage certificate in hand, ready to collect her belongings. There she finds Alan beside Sandra, his tenderness for her plain at last.
