Query: Kept me focused while on vacation in VEGAS!

Hilarious! This book was an impulse buy at the airport before my long flight, but I could not put it down! Not only did I laugh out loud in the plane from time to time, but I couldn't put it down for the entire time i was in Vegas!I enjoyed the characters, and the twists, and now i'm going right out to get the next one!
