Twenty-four hours

On her eleventh birthday, Emilia discovered she had the power to move between dimensions; a power that runs in the veins of her family since ancient times and that was inherited to her by her great-great-grandfather. The rules to use it are simple: Always come back using the same door you used to get to another dimension and never, never, spend more than a day on the other side, otherwise every memory of you would be erased in the world you belong to. But Emilia's power is a cherished asset since it holds the key to every world known.

And on her sixteeinth birthday, she's kidnapped by a witch who plans on using her power to become the ruler of all the universes. Trapped in a labyrinth of doors that behold unimaginable dangers, Emilia has only twenty four hours to come back where she belongs or become a long forgotten memory on the hearts of everyone she loves.
