The first book was about celery. This one is about cells. In the second year of UW-Madisonâ??s common book read program, Go Big Read, the university community will read “The Immortal Life of Henrietta Lacks,” by Rebecca Skloot. Last yearâ??s selection — “In Defense of Food,” by Michael Pollan — prompted a lively campus discussion on farming and food. Sklootâ??s book is a story about the sample of cancerous tissue taken from Henrietta Lacks, a poor black woman in Baltimore who died in 1951 from cervical cancer.
