Taking away books and book time has been one of our most successful consequences. I think you really just have to find what it is that really matters to the kid - the consequence has to mean something. And if the only thing at the moment that he/she cares about is books, by all means, i vote take 'em away. They will learn how to behave if they want to avoid the consequence. (Taking away wii lego games and/or books before bedtime are about the only consequence that work in our house at the moment.)
