Themes
Quick Assessment
This adult-market nonfiction follows the story of Henrietta Lacks, whose cancer cells were taken without her knowledge in 1951 and became the first immortal human cell line used in medical research. It addresses cancer illness and death, racial discrimination and exploitation in medicine, and the poverty her family endured while others profited, and it includes frank discussion of research conducted on Black Americans without consent. Best suited to mature teens and adults who can handle serious medical and historical subject matter.
