Lauren, Jack, Ruby and Billy live by the seaside with their mum and dad. But their parents are always arguing, and then their dad moves out. Lauren and Jack decide they have to get them together again. And so begins Operation Eiffel Tower ... in which the four children try to raise money to give their mum and dad a treat in an attempt to make them happier. First they want to send their parents to Paris, but quickly realise they can never afford that, so instead they set up a dinner for two under the Eiffel Tower in the local crazy golf attraction. But will it get their parents talking again? A funny and very moving story that tackles important issues with a light touch.
