Twenty years ago, Grace wanted nothing more than to be with Trent - a boy with a guitar and a lot of promises. Dorothy wanted nothing more than for her daughter to fulfil her potential. In a moment of heartbreak and fury, Grace makes a split-second decision to board a plane to London and put an ocean between them. There, Grace takes a job answering calls for a wannabe music mogul and sends her life on a dazzling trajectory, resulting in an illustrious career managing a megastar, large houses in glamorous places, two children (one who might be a sociopath but the other seems fine) and marriage to Ed . . . who would do anything for her. Anything but move back in. Now, Grace is dragging her kids and a particularly irritating dachshund to her childhood home, where Dorothy is waiting with a roast and inevitable questions about where it all went wrong. On a McDonald's pitstop, among fractious kids and a runaway dog, she bumps into a ghost from the past ... Trent.
