I am currently reading my way through a long list of science fiction and fantasy titles. (http://www.npr.org/2011/08/07/138938145/science-fiction-and-fantasy-finalists if you are interested in the list).
A hero with an incredible talent...for breaking things. A life-or-death mission...to rescue a bag of sand. A fearsome threat from a powerful secret network...the evil Librarians.
Alcatraz Smedry doesn't seem destined for anything but disaster. On his 13th birthday he receives a bag of sand, which is quickly stolen by the cult of evil Librarians plotting to take over the world. The sand will give the Librarians the edge they need to achieve world domination. Alcatraz must stop them!...by infiltrating the local library, armed with nothing but eyeglasses and a talent for klutziness.

Cute, funny, and smart. Add in a coterie of Evil Librarians, plus magical skills acquired through the wearing of lenses (i.e. glasses). Also very meta, in that the author talks directly to the reader. A lot.
Of course, working in libraries, I was predisposed to love this. (Although I shouldn’t—I should be suppressing this work, like a good Evil Librarian).
I would recommend it for children who are dismayed about needing glasses. I think it would be an encouraging book for them and make their glasses seem more like the useful tools that they actually are.
