---------------------------------------------------------------------- ---------------------This work is the result of a rigorous and thorough research, with a great amount of unpublished material (documental, graphic and oral testimonies), about the fascinating history of María Vinyals y Ferrés, born in 1875 in the Soutomaior Castle (Pontevedra). She grew up in a wealthy family, lived intense experiences and ended up becoming a prolific writer, a pioneer in feminism and a woman worried about the future of the society that surrounded her. In her private life, she would rebel against the chains of an ill-fated marriage.
