Ven, Roz, Olive and Frankie have been friends since school. They day-dreamed of glorious futures, full of riches, romance and fabulous jobs.
Twenty-five years later, Olive cleans other people's houses to support her lazy, out-of-work husband and his ailing mother. Roz cannot show her caring husband Manus any love because her philandering ex has left her trust in shreds. And she and Frankie have fallen out big time.
But Ven is determined to reunite her friends and realise the dream they had of taking a cruise before they hit forty. Before they know it, the four of them are on the high seas. But can sixteen days of luxury and indulgence distract from the tension and loneliness that await their return?
