For the New Orleans elite, the Les Masques Ball is sure to be the social event of the season―if they can avoid another dead Queen. When debutante Margot Landry was found dead the morning after her reign at last year’s ball, it was a tragedy, but not a shocking one. Margot was a wild child with a self-destructive streak, nothing like this year’s Queen, Lily LeBlanc. With a perfectly poised debutante on the throne, everything is going according to plan…until the ball is hijacked by a mysterious figure in a Jester costume. That night, Lily sends a text to three of the Maids on her royal court―her best friend, Vivian; her boyfriend’s sister, Piper; and April, her former frenemy―asking them all to meet the next morning. But Lily never shows up.

On the surface, these three debutantes don’t have anything in common except their exclusive private school and their ties to Les Masques. But soon, they realize why Lily brought them together: something dark is lurking beneath the glamorous surface of the debutante world, and it might be the reason she disappeared. And the further the girls dig, the more they begin to suspect that Margot’s death may not have been an accident―and that Lily may be next. When the Jester starts threatening to expose their own secrets, this unlikely trio must team up to uncover the monsters behind the Mardi Gras masks―before they’re left with another dead debutante.
