Claire and Matt are no longer together but decide that it would be best for their daughter, Scarlett, to have a “normal” family Christmas. They can’t agree on whose idea it was to go to the Happy Forest holiday park, or who said they should bring their new partners. But someone did, and it’s too late to pull the plug. Claire brings her new boyfriend, Patrick, a seemingly sensible, eligible from a distance Ironman in Waiting. Matt brings the new love of his life, Alex, who’s funny, smart and extremely patient. They all drink a little too much after Scarlett’s bedtime, overshare classified secrets about their pasts…and before you know it, their holiday is a powder keg that ends where this novel begins --- with a tearful, frightened call to the police.
