A conversation between the winners of the 2016 and 2017 Baillie Gifford Prizes for non-fiction. France tells Sands the riveting, powerful and profoundly moving story of the AIDS epidemic and the grass-roots movement of activists, many of them facing their own life-or-death struggles, who grabbed the reins of scientific research to help develop the drugs that turned HIV from a mostly fatal infection to a manageable disease.
