Is this a "clean" book? I recognize we all have different tastes and I'm fine with that and not trying to "judge" anyone. But for me, I prefer to avoid reading: - large amounts of foul language - graphic violence - sex scenes or strong sexual innuendo. For reference, Brandon Sanderson's books are at about the right level for me in terms of "cleanliness". I'd really appreciate anyone giving me a quick rating. Thanks!
