When her best friend's house is threatened with repossession, young Annie Jenkins is full of ideas to save the home: selling her appendix on eBay, winning the lottery, facing down the bankers... anything to keep Jason from moving. Unfortunately Jason's out-of-work dad blows up at the smallest things, and he's not very happy with Annie's interventions, which always seem to get them into more trouble. But when Annie tracks a lost treasure to Jason's back garden, she's sure the booty will be enough to save Jason's family. Pirate treasure in the Midlands seems far-fetched, even to Annie, but it could be the answer to all their problems. Now all she has to do is convince Jason. As the two hunt for answers and the pressure gets to Jason and his family, Annie discovers that the best-laid plans aren't always enough and there are worse things than moving away.
