This genre-defying narrative combines history, science, memoir, and biography. You’ve been affected by the HeLa cells derived from Maryland woman Henrietta Lacks, called “immortal” because they thrive in the lab: they’ve been used to develop the polio vaccine, cure cancer, and fight the flu. But her family didn’t discover anything about the cells until more than twenty years after her 1951 death. Skloot unearths the incredible story of how that happened, weaving the tale of the HeLa cells together with Lacks’ personal narrative.
