Journalist Haley Cohen Gilliland's book A Flower Traveled in my Blood documents the incredible determination of the Abuelas de Plaza de Mayo - a group of Argentinian grandmothers who banded together to find their lost children and grandchildren following a series of kidnappings by the military junta in the late 1970s.
Haley speaks to Susie Ferguson about why this was a story that she just had to tell.
