Back in 2009, a nonfiction book was published that spent more than a year on the NY Times Bestseller List: The Immortal Life of Henrietta Lacks by Rebecca Skloot [616.0277 SKL, AB/CD 616.0277 SKL, eBook].
HBO has adapted the book and it will be shown on Sunday, April 22. Henrietta Lacks' daughter is played by Oprah Winfrey. Once the movie has aired, I'm sure there will be renewed interest in the original book. If you haven't already read the book, I'd suggest you do it now!
