Langston Hughes' Weary Blues is amazing, but I'm no expert on poetry.
For non-sci-fi, my favorite fantasy book I've read recently was "The Lies of Locke Lamora" (and its sequels) by Scott Lynch. Another is "Dirty Jobs" by Christopher Moore, a bit on the Pratchett-inspired side of things.
I also recently finished Felicia Day's memoir, "You're Never Weird on the Internet," which I highly recommend.
Ideas from that book come up once a week in conversations.
Excellent storytelling, humour and slice of life human drama. It's just amazing how Junot Diaz tells of the tragedy of one family and the fukú curse that haunts them over generations.

Gorgeous, funny writing. The story spans roughly half a century and moves between Europe and the United States.
