Query: Sara and VI do it again!!

I have anxiously awaited a new book by Sara Paretsky, about VI Warshawki. And I wasn't disappointed. Welcome Back, VI! and Welcome Back, Sara Paretsky! I tried to read this book slow, so it wouldn't end, but stayed up half the night to see how VI gets outta this one! Can't wait for her next exploits.
