Mara thought her world was safe. Her days were simple, her daughter Anna her only joy. But in a single night, everything shatters-Anna vanishes through a door that should not exist, leaving Mara with nothing but a cold iron key and the crushing silence of an empty home.To bring Anna back, Mara must step into a hidden world where every choice comes at a price. Three doors stand before her. Behind each is a piece of what she longs for most-but each one demands something from her in return. The deeper she goes, the more she learns: this is not only a trial of love, but a trap designed by something-or someone-who already knows her fears.There is a doctor who wants to help, and a Matron who claims to hold all the answers. But neither is what they seem. And in the shadows, a darker figure waits-watching, patient, and ready to take everything if Mara falters.How far would you go to save the one you love?And when every door takes something from you... what will be left when you finally open the last one?
