Blood Matters by Masha Gessen is what I imagine you would get if you were to immerse yourself in the inner monologue of a fact-obsessed individual’s decision-making process. The book opens with Gessen learning their mother has died of breast cancer, followed by a jump in time to Gessen getting a positive BRCA1 mutation test result. These two events set the tone for the book in which Gessen examines through the past and present lens how genetics, and our knowledge of our own genetics, has shaped how we view ourselves, the world, and our connections to each other. In doing so, Gessen lends a perspective not often seen in journalistic or scientific writing — the Jewish one. As readers, we get to learn about scientific concepts in the frame of Jewish history and anecdotes, as well as how these concepts and the ideologies born from them have reverberated through history. For me, Gessen’s need to know all the facts before making a life-changing medical decision was extremely relatable, and I think many others will find it easy to empathize with Gessen’s experience(s).
