This was a very enjoyable series, and I was satisfied with the open-ended way the author left it. Though I found Grossman's writing style pleasing, I found that I never got attached to any of the characters. I liked them all well enough, but in a more detached way than usual, especially considering that I'd just followed some of them through three books.

And just a side question: After Quentin was kicked out of Fillory by Ember, why did he never spend any time in Venice? That beautiful Palazzo was never mentioned again...not to be overly materialistic...

Anyway, these books were fun, and I'm glad I read them.
