The Wellesley Free Library is partnering with Massachusetts Bay Community College to encourage area residents to read a popular nonfiction book about civic engagement. The townwide Wellesley Reads Together program and MassBay’s One Book campaign are both promoting “The Pact,’’ a New York Times bestselling memoir. It explores three African-American doctors’ days as students at a magnet high school in Newark, where a presentation had led to a promise by the three friends to help one another succeed. The book’s authors — Rameck Hunt, Sampson Davis, and George Jenkins — have appeared on “Today“ and “The Oprah Winfrey Show,’’ and have also been featured in a New York Times article. Their book will be the focus of several free events and discussions for participants in the reading program, according to the library.
