I would recommend any nonfiction work of James Baldwin. He is masterful in his reasoning and elegant, and at times surprisingly abrupt, in his prose. Years ago when Baldwin was still alive, I read his magnum opus, The Price of the Ticket: Collected Nonfiction, 1948-1985, marveling at how adept he was whether reflecting on race, jazz, language, politics, sexuality, literature, economics, or urban life.
The Library of America edition, pictured below, collects that volume along with nine more essays. The Cross of Redemption: Uncollected Writings includes speeches, letters, and book reviews, among other pieces, which did not appear in Baldwin's earlier books.
Collectively these books offer a deep look into the American psyche during Baldwin's half-century of remarkable composition, a key examination of a writer's unique style, and a powerful testament to his enduring influence on world literature.
