The Magicians by Lev Grossman is one of my favorite books! I've recommended it to any adult who loved Harry Potter and after five or so people promised to read it after they finished such and such and so and so and then never picked it up, I put it on the book list.
It took 7 months, but it was finally chosen!
A warning before you run to the store and go get it right now. It's the adult version of Harry Potter. And I don't mean it just has curse words and sex scenes combined with magic (which it does). It also has a quarter-life crisis outlook on life. So if you think that hard work and talent will help everyone achieve all of their ambitions, then this book will probably piss you off.
If you recently graduated and have put in the time, got decent grades, and consider yourself smart and hardworking, but have been trying to find any job for half a year - let alone one you can stand - then this book is for you.
Being a magician in Grossman's world is hard work. It's for Type-A personalities who obsess heavily over details and memorization and will do the same thing over and over again until it's right.
Unfortunately, those character traits rarely let one achieve happiness. Especially if the world doesn't resolve itself into a neat little bow once you've succeeded. Like real life.*
The book is about Quentin's Coldwater discovering his magical traits at 17, his life at Brakebills (a college for magicians,) and his search for Fillory. Coincidentally, Fillory is a magical world created by Christopher Plover in the 1930s. It sounds a lot like Narnia, but it's a separate and real series.
So if my warning didn't put you off, the go run to the store and get it right now! Also there's a sequel!
It inspired 3 hours worth of discussion in my book club by the way, so I'm not the only one who liked it and wanted to talk about it.
*I know it sounds like I'm depressed. I'm not. I've just watched a majority of my friends struggle to get some of the same opportunities that I just fall into. While I definitely do what I can to make thing work and deserve it, most of my success I blame on luck.
