Gilliland’s first book (of many, we should hope) tells the remarkable story of the Abuelas de Plaza de Mayo (“Grandmothers of the Plaza del Mayo”), a group of courageous grandmothers who spent decades searching for their stolen grandchildren. Their name refers to the Plaza de Mayo in Buenos Aires, where the grandmothers held weekly marches outside the presidential palace, demanding justice and answers. As for the stolen children, the official count is 392, though the Abuelas believe the figure could be as high as 500. In certain cases, children had been adopted by loving families who believed the children had been abandoned. The Abuelas remain united in their struggle to this day and Gillibrand does a masterful job conveying their extraordinary story.
