Right now, I'm reading Kafka's The Process. For some inexplicable reason, I find it hilarious.
Usually, Kafka (for example, The Metamorphosis) is perceived as conceptual and depressing, but The Process cracks me up with its satire on society and charming absurdism.
From my recent sci-fi/fantasy reads, I highly recommend Roger Zelazny's 'Lord of Light.'
One of my new favourite books.
