Back to Fillory, and boy is it dark. Like a lot of other reviewers, I liked this better than the first book, The Magicians, and I really liked The Magicians. I heard that Grossman is writing a third and final book, and I can't wait for more.
The Magician King continues the adventures of Quentin Coldwater, the douchiest douchebag to ever enter the multi-verse. He's slightly less whiny in this installment, and half of the book is focused on Julia, so that already makes it better than the first book. Quentin, Julia, and the two other characters whose names I can't remember are the Kings and Queens of Fillory. Hey, just like Narnia! Adventures ensue. Seriously, I don't like recapping an entire book. I always feel like I'm either giving too much away or not doing it proper justice.
If you like epic fantasy turned on it's side and made disturbingly dark, then this is the book for you. I enjoyed it more than I thought I would.
