Truth or Dare . . . (You're invited to a Creepover)

During a round of Truth or Dare, Abby Miller confesses her crush on Jake Chilson. The only people who know her secret are her friends at the sleepover—and whoever sent her a text message in the middle of the night warning her to stay away from Jake…or else!
But Abby isn’t going to stay away from Jake, especially not after he asks her to the school dance.
As the night of the dance comes closer, some very creepy things start happening to Abby. Someone definitely wants to keep her away from Jake. Is it a jealous classmate or, as Abby begins to suspect, could it be a ghost?
