The Barnes family is in trouble. Dickie's once-lucrative car business is going under - but rather than face the music, he's spending his days in the woods, building an apocalypse-proof bunker with a renegade handyman. His wife Imelda is selling off her jewellery on eBay while their teenage daughter Cass, formerly top of her class, seems determined to binge-drink her way to her final exams. And twelve-year-old PJ is putting the final touches to his grand plan to run away from home. Where did it all go wrong? A patch of ice on the tarmac, a casual favour to a charming stranger, a bee caught beneath a bridal veil? Can a single moment of bad luck change the direction of a life? And if the story has already been written - is there still time to find a happy ending?
