Mercedes Salisachs (Barcelona, 1916-2014) was a writer better liked by her readers than by the critics. Due to her upper-class background, she was considered the chronicler of the Barcelona bourgeoisie. During her long career, she wrote nearly 40 novels, stories and essays. Among them are La Gangrena [Gangrene, 1975], inspired by the loss of one of her sons in a car accident, and for which she received the Planeta book prize; and her autobiography which she wrote very early, in 1981.
There is a short Wikipedia article and an official website, both in Spanish. Amazon lists Seeds of Silence (2007) as still available in English; according to the official website there were earlier translations to English such as The Eyes of the Proud (1960).
