Publisher's Synopsis
Pranks are the best thing about Halloween -- until a ghost pulls one on you.
When eleven-year-old Lyssa Klarken discovers the legend about her ballet school being haunted is true, she thinks she's won the candy-filled jackpot. But treats turn to tricks when Nadia, the ghost of a star ballerina, starts pranking her. Nadia only agrees to leave Lyssa alone if she frees her from her unfinished business. There's just one problem: Nadia can't remember what that is. Lyssa has six days to figure it out and save Nadia from torment. If she fails, the tables will turn: Lyssa will be haunted for the rest of her life. Can she solve the mystery before the curtain rises on October 31st?
