The Plum books are never meant to be high literature. They are exactly what they are meant to be: fast, fun and pretty mindless entertainment with characters we've come to know.
The premise of 'Look Alive Twenty-Five' is even wackier than usual but what stood out is what's missing: Stephanie's beleaguered Mom and her adorably crazy-wise Grandma.
I laughed with the ketchup/fryer scene. So Stephanie/Lulu.
