Sibling rivalry has crossed many an ocean. ... When Constance Wright arrives at her family's summerhouse on the Mediterranean island of Santerre for her father Ross's memorial, she hopes that boyfriend Jim, the New York investment banker on her arm, will boost her status in the family. Between her ravishing sister, Isabelle; her ageless French stepmother, Odette; and her English stepsisters, former model Lucy and famous artist Jane, there's a lot of competition for attention -- not to mention double beds. ...Now it's time to sink or swim. What she hadn't counted on is the attraction Jim develops for one of the other women in the house...and the affinity she feels for the mysterious writer who moves in next door. As liaisons shift and tension soars, Constance finds that she's not the only one in the house whose love life is in turmoil. Complicating matters is the discovery of a Swiss bank account that Ross left behind. Now, the women of this eclectic family are about to learn more than they ever wanted to know about each other, their father, and themselves.
