Thirteen-year-old Natalie Gallagher is trying to escape: from her parents' ugly divorce, and from the vicious cyber-bullying of her former best friend. Adrift, confused, she is a girl trying to find her way in a world that seems to either neglect or despise her. Her salvation arrives in an unlikely form: Bridget O'Connell, an Irish maid working for a wealthy Boston family. The catch? Bridget lives only in the pages of a dusty old 1920s diary Natalie unearthed in her mother's basement. But the life she describes is as troubling - and mysterious - as the one Natalie is trying to navigate herself, almost a century later.

As the troubles of a very modern world close in around them, and Natalie's torments at school escalate, the faded pages of Bridget's journal unite the lonely girl and the unhappy widow - and might even change their lives forever.
