the magician king, by lev grossman
I never even reviewed the prequel to this book – The Magicians, Hogwarts and Narnia as reimagined by Curtis Sittenfeld – because the ending made me so mad. The hero-protagonist made a decision that was ethical and unselfish, and then (spoiler!) he turned around and did the opposite thing just ’cause.
Imagine my surprise! then, when this is actually addressed in the sequel, where escapist fantasy worlds suddenly cease to be consequenceless and people have to do the right thing, at whatever cost to themselves!
Also! You know how I do that thing where I say “There is a MUCH more interesting book to be written about what happened to Secondary Character X over the course of THIS book!” This is that book! I shall call it HERMIONE GRANGER STRIKES BACK.
