Four friends one big secret. . . and the journey of a lifetime. It's nineteen years since they stopped speaking to each other but now Morgan needs to contact her three best friends from school: Paige Emily and Tiff. Her teenage son wants to meet his dad and Morgan can't ignore his requests any longer. And Paige Emily and Tiff all knew what actually happened back then. Even if that was what led to their friendship group falling apart they're the only people Morgan can think of who might be able to help her find the man who disappeared without a trace before she could tell him she was pregnant. Can Morgan persuade her old friends to go on a road trip to track him down? As adults - with marriages children and a whole bucket-load of their own problems - will they be able to work together to solve the mystery? And if so - just when forgiveness for the past looks like it might be possible - how will they cope with the biggest shock of all?
