Mário Cabral - O Mistério da Casa Indeterminada

The island house, nestled in the shadow of the mountain, seems haunted ever since the father's death that terrible winter. Why did the four siblings' happy childhood give rise to such profound existential turmoil? What wrong did they do to deserve such extreme punishment?
"The Mystery of the Undetermined House" is a classic novel, not only in form but above all in its themes: what is life, what is death, what is love, what is art—and, for Sofia Georgina, the heiress who finds the key to the mystery and projects the house into the future with hope, what it means to be a woman.
