No book is going to be able to teach you klezmer. It's not a matter of moving your tongue this way or that, really, though that is what happens. It's a matter of getting the sound and emotion which will naturally come to any clarinetist or other musician who understands klezmer.
What you need is not a book but recordings. I recommend Rhythm & Jews and other early Klezmatics recordings, the Maxwell Street Klezmer Band, and The Klezmer Conservatoire Band. Perlman Plays Klezmer, by Itzhak Perlman, features some great bands (including some named above), and also his great playing in a surprisingly adept klezmer style.
