"The World According to Garp" by John Irving. Again, one of my favorite authors, one of his best books, but I really recommend almost all of his books.
"Starship Troopers" by Robert A. Heinlein. Just read this a couple weeks ago, highly recommended.
"A Walk in the Woods" by Bill Bryson. Just another of my favorite authors, I recommend any of his books if you like travel books. Very witty and well written stuff. A Walk in the Woods is probably his best known book about his attempt to thru-hike the AT.
"Story of Your Life and Others" - Ted Chiang. Really really good sci-fi short stories. Some great stuff. The movie Arrival is based on the title short story, Story of Your Life.
Honorable Mentions (from things I've read in the past year): "Meddling Kids" by Edgar Cantero "The Island of Dr. Moreau" by H.G. Wells "Furiously Happy" by Jenny Lawson
I could keep listing books, but this is probably already excessive.
