Nother Poll

 I am once again teaching Writing Fantasy and Science Fiction in the fall semester.  I want to upgrade my reading list.  I am pretty familiar with classic or old fantasy and SF but less so with cool new stuff.  I know that a college syllabus ought to have a slightly musty or stuffy air about it, but still -- can you tell me what ONE book written in the last, say, 10 or 15 years (yes, I know that that's already "old" to many) you would not want young readers to miss?  (One only because I'm afraid of too many to manage from widely-read friends.)
