Moscow, 1989. Twelve-year-old Zoya's biggest concern is dodging the school bully—until a violent encounter catapults her into another world. She awakens in Paris, in the life of a girl who looks exactly like her.

As the Soviet Union teeters on collapse, Zoya begins slipping between two worlds:

✨ A crumbling Moscow, where her family struggles through the chaos of a vanishing empire

✨ A shadowy Paris, where hidden dangers and buried secrets threaten to consume her

✨ And an uncanny apartment that might be the key to it all

Pursued by a mysterious doctor and haunted by questions of identity, Zoya must unravel the truth behind her double—and decide which life is truly hers before time runs out.
