I've begun reading On Juneteenth, a book of essays by the prominent historian Annette Gordon-Reed. The book was published in May of 2021, the month before Juneteenth was designated a federal holiday.

Ms. Gordon-Reed is perhaps best known for her 2008 book, The Hemingses of Monticello: An American Family. The book received the 2008 National Book Award for Nonfiction, and, in 2009, the Pulitzer Prize for History.
