5 kids, 1 prophecy.
What would you do if you found yourself trapped underneath your school? Scream, run, find a way out, you get the idea. But what would you do if you found out that you were meant to be trapped? That's exactly what happened to Mirabelle Santiago, who fell deep beneath Cobblestone Valley Middle School while walking down the halls. But the odd thing is, Mira isn't the only one trapped, 4 other kids also fell in due to some strange prophecy.
Can the group put their differences aside and work together to try and break the prophecy?
A chilling, thrilling mystery you don't want to miss!!!
