This is a story about the world on the other side of the mirror. A world created by two twin sisters, Kat and Elle. A small universe in their own home, a repository of fictional pirate ships, clowns and witches. Ten years later, one of the sisters must return to this world...

When the adult Elle disappears, Kat sets out to find her. She has to step on the threshold of the huge house, full of ghosts and childhood nightmares, where the sisters grew up. Someone is leaving Kat clues. Someone who knows that the world of their childhood is a fiction. A fiction in which two little sisters wanted to hide from very real violence. Back then, long ago, they miraculously managed to escape. Now Kat has to save her sister. But from whom? Who is the monster that has crawled out from under the bed of their childhood memories? Kat must remember what once happened within the walls of the house.
