Amelia and her friends are taking part in a competition to visit Pumpkin Paradise Park – the most bloodcurdingly brilliant theme park ever! All they have to do is sell as many cookies as possible.

Where have everyone’s memories gone? And how can Amelia save them when they have all forgotten who she is?
