When Londoner Becky Greene moved to Ireland, she was ready for a fresh start - and to leave her dysfunctional family far behind. But when she discovers that she's pregnant, after a one-night stand, all of a sudden she suddenly has more than herself to think about.

Fast-forward four years and now her daughter Lilly is asking questions about her father. While tracking down high-flying property developer Dennis Prendergast is the last thing Becky wants to do, she knows that Lilly has a right to know who her father is. But when Becky finally locates Dennis, she discovers that his life has taken a very different route. And finding out he has a daughter is definitely not in his five-year plan.

Can people ever really change? As Becky comes to know the person Dennis is now, and a little more about herself, she begins to think that maybe people can.
