Roslindale branch Online Race and Inclusion Book Discussion — ‘Caste’: 9:15-11 a.m. or 2-3:45 p.m. Jan. 30. The group will discuss Isabel Wilkerson's latest book, “Caste: The Origins of Our Discontents.” Wilkerson gives a portrait of an unseen phenomenon in America as she explores, through an immersive, deeply researched narrative and stories about real people, how America today and throughout its history has been shaped by a hidden caste system, a rigid hierarchy of human rankings. She is also the Pulitzer Prize-winning author of “The Warmth of Other Suns.” The discussion will be led by local educator Josh Frank. Because of the book’s popularity, there will be two group sessions with 20 participants each on the three dates. To register, email JP Branch librarian Laura Pattison at jamaicaplain@bpl.org and write "Caste Book Discussion" in the subject line when you RSVP.
