Sometimes the greatest spectacle hides the darkest secrets…

In an alternate London, the city's Theatre District is a walled area south of the river where an immersive production—the Show—has been running for centuries, growing ever bigger, more sprawling and lavish. The Show is open to anyone who can afford a ticket but the District itself is a closed world; even the police have no jurisdiction within its walls.

Juliet's mother died when she was a baby. Brought up by her emotionally distant father and even more distant stepmother, she has never felt wanted. It's only when her father passes away that Juliet, now nineteen, learns her birth was registered in the District. Desperate to belong somewhere at last, she travels to London where she hopes to unearth the truth about her identity, her mother's death and her father's years of silence—and claim her birthright.

But in the District, there is only one central truth: the Show must go on. And in a world where illusions abound, and powerful men control the narrative, Juliet has no idea of just how far some will go to ensure certain stories are never told…

For fans of The Miniaturist and The Doll Factory, The Theatre of Glass and Shadows is a place where nothing is as it seems.
