Madeleine's the newest arrival at the famed Dario Quincy Academy of Dance. She's worked hard to gain admission, and she's determined not to lose her scholarship. That means not asking too many questions when her antique necklace goes missing, and certainly not breaking curfew. So how does she find herself exploring the creepy tunnels that run underneath the school?

As if rivals at dance practice weren't bad enough, Madeleine begins to suspect that there's an ancient evil on the academy grounds. And when Madeleine and her rivals join together, sneaking out at night to explore the school's depths, the evil might just follow them back upstairs.
