It ain’t easy being king. Or it’s too easy. In The Magician King, the follow-up to Lev Grossman’s The Magicians, Quentin Coldwater and his friends have beat the bad guys to become the kings and queens of Fillory, and it’s getting a little boring. But when Quentin and Julia are dumped back in the real world, they have new problems to tackle. Grossman will be in discussion with Erin Morgenstern, author of The Night Circus.
