Steph has spent decades building a family with her husband Mal and putting their family first. She is the glue that holds them all together and she has convinced herself that she?s been happy ? most of the time. But as she stands at her birthday party watching her husband talking about a wonderful marriage she doesn?t fully recognise, the doubts that she has been pushing down for so long begin to grow ? After the party, as Steph tries to gather her courage to leave Mal, she receives a letter from her old friend Evie. Steph hasn?t spoken to Evie since a sunny weekend on a holiday beach 20 years earlier, when the two friends said things to each other that could never be unsaid. And now, Evie is seeking a reunion and a way to repair the friendship. But this reunion threatens to reveal a secret that could destroy two families.
