The Magicians (The Magicians #1)

Like everyone else, precocious high school senior Quentin Coldwater assumes that magic isn't real, until he finds himself admitted to a very secretive and exclusive college of magic in upstate New York. There he indulges in joys of college-friendship, love, sex, and booze- and receives a rigorous education in modern sorcery. But magic doesn't bring the happiness and adventure Quentin thought it would. After graduation, he and his friends stumble upon a secret that sets them on a remarkable journey that may just fulfill Quentin's yearning. But their journey turns out to be darker and more dangerous than they'd imagined.
