Iain M Bank books
I've loved everything I've read so far from Iain M Banks, but "The Use of Weapons" stands out above other others as an absolute materpiece, with one of the greatest twists ever written. It's one of the least sci-fi-ey of them, with less focus on the technology. If you love that side of Sci-Fi, maybe try "Matter" first.
I haven't read any of the Non-SF, but I've heard that "The Wasp Factory" is considered a modern classic.
