Peter and Molly want to keep the starstuff away from Black Stache and the Others. But the Others and Black Stache keep trying to kill them. So they befriend the Indians and the Mermaids and fight to get the chest safely to the Starcatchers. Then Molly and her father go back to England and Peter, James, Tubby Ted, Thomas, and Prentiss stay on the island.
I could not stop reading this book! I could imagine everything in this book as it was happening and it was mysterious and action-packed. The transformations that the treasure chest caused were very strange but at the same time they were interesting. There wasn't a moment in the book where something exciting didn't happen, there was always either a pirate trying to catch them or Slank trying to catch them or a battle between the pirates and the boys.
