Juneteenth by Ralph Ellison. One of the two posthumously cobbled together versions of Ellison's unfinished second novel.
The Genius of Shakespeare by Jonathan Bate. Not, as the title suggests, a critical analysis of Shakespeare's work, but a broader look at Shakespeare as historical figure, writer, and international cultural phenomenon.
The Swan Book by Alexis Wright. This has been on my radar since it was published to acclaim in 2013. I've heard that the audiobook is fantastic, too, and potentially a more approachable way into what is reputed to be a challenging novel.
Christmas Stories edited by Diana Secker Tesdell. I have a bunch of Christmas anthologies but they're all ghost/weird stories. Christmas Stories is at the more "literary" end, with stories by Gogol, Willa Cather, Elizabeth Bowen, Truman Capote, and so on.
