What if one day you woke up to find you've taken the place of your double - a doppelgänger you never knew existed? And what if you liked their life better than your own?
Twelve-year-old Zoya Kassatkina never dreamed of going to Paris. In 1989 Moscow travel abroad is a privilege reserved for a select few, and her family isn't one of them.
But when the biggest school bully takes it too far, Zoya is knocked unconscious and wakes up ... in Paris.
There, everything is perfect. She even has a best friend! Zoya sets out to enjoy Paris to the fullest, except it's not really her life. She has taken the place of another girl, who has disappeared.
Before she can understand the full impact of the switch, Zoya is thrown back to dreary Moscow. Zoya will do anything to get back to Paris and employs the help of her only friend to do so. But first, she needs to understand how she ended up in Paris in the first place.
Did she discover a parallel universe? Is she part of the metaverse? Did she travel in time? Or was it all just a dream?
As Zoya seeks answers, she learns about the multidimensional world and transforms her reality, as well as that of those around her.
