"JoJo's friend Miley is throwing a costume party, and JoJo and her friends have been planning their costumes for weeks! The only question on their minds: How much glitter is too much glitter? (Answer: No such thing!) When they show up at Miley's on the night of the big bash, everyone's decked out and ready to party. But who is the mysterious visitor in the ghost costume with a penchant for candy apples? When JoJo and her friends pull a few tricks in order to unmask their veiled visitor, they find they're in for a celebratory treat!"-- Provided by publisher.
