I'm not sure why Maria Semple's writing feels so different to me, but there is something about it that for lack of better words, I would describe as refreshing, surprising and modern. Even with a somewhat unlikable main character (she walked dangerously close to the whiny-self-absorbed-spoiled-chick-lit girl that I hate), I was still propelled forward at a fast pace, wondering what will happen next.
