Not yet fifteen, Gabriela Amador Prieto has been cast out of the family home by her father, who believes her shameful behaviour has tarnished the family honour. All traces of her have been removed, and not even Lucy, Gabi’s older sister and best friend, knows where she is. Furious at her father and desperate to find her sister, Lucy leaves their small town in Baja California, Mexico, and sets out for the capital to track Gabriela down. While Lucy ventures deep into Mexico City’s most dangerous neighbourhoods, back at home her family members--her brothers, her mother and father, and her brother-in-law, Antonio--struggle with their own roles in Gabi’s banishment. The Good Sister presents a vibrant, captivating portrayal of contemporary Mexico, and of a family torn apart by a father’s hypocrisy. Engaging and emotionally rich, this novel is a fascinating exploration of betrayal and steadfast devotion, and the ways in which our own intolerance can harm what--and whom--we love most.
