1939, Europe on the brink of war. Lily Shepherd leaves England on an ocean liner for Australia, escaping her life of drudgery for new horizons. She is instantly seduced by the world onboard: cocktails, black-tie balls and beautiful sunsets. Suddenly, Lily finds herself mingling with people who would otherwise never give her the time of day.

But soon she realizes her glamorous new friends are not what they seem. The rich and hedonistic Max and Eliza Campbell, mysterious and flirtatious Edward, and fascist George are all running away from tragedy and scandal even greater than her own. 

By the time the ship docks, two passengers are dead, war has been declared, and life will never be the same again.
