It's been a couple years since I've read this book and I don't remember much, but from what I do remember and from what you said in the review, it was boooooring. The character stuff from Ax didn't become important until the very last few books (and even then, it wasn't as good as his stuff in book 52), and there was a ridiculous amount of padding. That long, ridiculously drawn-out passage where Jake is going over the specs of the airplane is proof enough of this.
