Amelia Fang and the Memory Thief

Meet Amelia Fang, everyone's favorite vampire. Amelia and her friends are taking part in a competition to visit Pumpkin Paradise Park--the most blood curdingly brilliant theme park ever. All they have to do is sell as many cookies as possible. But the creatures of Nocturnia has begun to act very strangely. No one can seem to remember anything--including their own names or even Amelia's birthnight party. Where have everyone's memories gone? And how can Amelia save them when they have all forgotten who she is?
