Joan just wanted to prove herself as good a jewel thief as her sisters. But a threat to expose her family means Joan has to pull off a near-impossible heist.

Unfortunately, this means investigating a murder that hasn't happened yet. Worse, it means dealing with a troubled – and possibly cursed – musical.

Not knowing who or what she can trust, Joan must craft her own strategy through the chaos to come. And if she's going to pull of this heist and protect her family's secret, she'll first have to solve the mystery around the murder – all while dodging dancers and dangers.
