David Scrimshaw reviewed Codex by Lev Grossman
Review of 'Codex' on 'Storygraph'
3 stars
If you've read all the [book:The Magicians|6101718] books, which you should if you had any affection for the Narnia books, you might want more Lev Grossman.
This one moves along and the characters are interesting. But if you want to feel like you know what's going on when a story ends, I think you have to be smarter than me.
I don't know if this really qualifies as fantasy.
