The Magicians: Lev Grossman

In a secret world of forbidden knowledge, power comes at a terrible price...
Quentin Coldwater`s life is changed forever by an apparently chance encounter: when he turns up for his entrance interview to Princeton University, he finds his interviewer dead - but a strange envelope bearing Quentin`s name leads him down a very different path. Instead of Princeton, he finds himself invited to study at Brakebills - a secret college of modern-day sorcerers.
Quentin plunges deep into a secret world of obsession and privilege, a world of freedom and power; and for a while, it seems to answer all Quentin`s desires. But the idyll cannot last. There are others powers than sorcery, powers that are as seductive as they are dangerous - and when the illusion of safety shatters, Quentin is drawn into a world far darker than he ever imagined.
After all, power corrupts. No exceptions.
