The novel describes the critical experiences and discoveries of an adolescent girl left to her own devices: her mother is a prostitute and her sister is a striptease dancer in a Madrid club. The main protagonist of the story, however, is the redeeming innocence through which everything acquires a new meaning. Reminiscent of the heroine of Flaubert's novel, she is only ever introduced as Katia's younger sister; we never even know her name, but her figure of childish innocence is both moving and unforgettable for those who come into contact with her in the course of the novel.A novel that reveals an author of surprising literary and intellectual maturity, in spite of his youth. Barba is a smart stylistic author who avoids following recent literary fashions.
