11-year-old Albertine is rather transparent and fragile, unlike the rest of her family members, who are full of color and fancy. Their latest whim: this strange house to which her mother decided to move. A fairy-tale house for children, teeming with mysteries in the basement and attic. And in the basement, as it just so happens...
In the basement... there’s a door, which only Albertine has found. A door that leads to an Underworld and its curious inhabitants.
