I'm always reading something, usually multiple books at a time.
My absolute favorite book of this trilogy, Grossman has pulled off a true hero's journey for Quentin, while giving rich character development to the other members of this book's ensemble cast. The mature version of himself that Quentin becomes by the end of this installment feels almost like a completely different person, compared to the magic-obsessed teen he was at the beginning of the first. My favorite thing about his growth is the role of empathy. There is so much power in that empathy--but the good kind of power. A great payoff to readers of the trilogy.
[And yes--I created this edition, because the one I listened to did not exist here. ::sigh::]
