1943: Europe is at war - but neutral Ireland is isolated from the storm. In a sleepy coastal village south of Dublin, 18-year-old Aileen Sweeney meets soldier Niall O'Rourke at a dance, and the spark between them soon ignites a powerful love.

But when Niall makes a life-changing and contentious decision, Aileen’s hopes and dreams fall apart. In an instant Niall is transformed from dashing suitor to social outcast, and the fallout leaves each of them navigating the consequences alone. Putting her innocence behind her, Aileen must make her own tough choices - choices that will set the course of the rest of her life.

Aileen and Niall have promised to stay true to each other while they’re apart, but in a world at war and where nothing is certain, can their relationship really survive the distance of an ocean?
