The Sandman Library, Neil Gaiman
The Sandman Library is a collection of ten main graphic novel plus a number of spin-offs. It tells the story of Dream of the Endless, personifications of fundamental aspects of the universe. This was my first real exposure to comics as an adult. I'd heard about the series a lot but hadn't happened to pick it up. It tells a wonderful story. Really it tells wonderful stories because there are many central characters. This is definitely worth reading.
