Billie Proudman is Nina's boisterous elder sister. An apprentice in their father's real estate business, Billie is a force to be reckoned with. Bold, brassy and incapable of lying. While Nina was good as gold, Billie was the wild child; the black sheep who strayed from the flock. But the clock is ticking for Billie, who is determined to put her wayward youth behind her, to straighten up and fly right, to make something great of her life. Adventurous and extroverted, Billie's tough exterior masks a very soft centre, and she will go to almost any length to protect the things she cares about. Recently married to long term boyfriend Mick, Billie's determined to have a baby with a little help from her extended family.
