Nancy Drew is one of the chaperons on a field trip to Kings Common Amusement Park (owned by the Royal Chocolates Company). Nancy's friend (Bess) wins the grand prize at the park by having the winning million-dollar candy wrapper. But when they go to collect the prize they're told that someone else has won. But how can this be when Bess has the grand prize ticket? There is only supposed to be one grand prize winner. Could there be a spy at Royal Chocolates trying to ruin the company? After some attempts on their lives, Nancy decides to do some investigating on her own...

This was a fun, quick read. I loved all the delicious chocolate references, the great setting, which takes place mostly in an amusement park, the mystery... A very entertaining read. ( )

Okay book. Not great. A very interesting plot, and it was really interesting to figure out HOW the winning wrappers got faked, and especially when they suspected Andrea... But it was blaringly obvious who the real culprit was, especially knowing the usual ND plot formula. ( )
