Children of the Night Daily News by Sherryl Connelly Lauren Weisberger got a Bad Girl rep with The Devil Wears Prada. It was misleading: The truth is she writes happy-ever-after tales in which a young innocent is tossed into the vicious and vacuous swirl of the Manhattan scene only to find shore by story's end. Weisberger, who seemingly skewered her former boss Anna Wintour in Prada, sets her second novel, Everyone Worth Knowing, in Lizzie Grubman's world. Bette Robinson quits her banking job and stumbles into a new life when she becomes a Power Girl at the nightlife public relations firm Kelly & Company. The daughter of crunchy-granola parents, Bette just doesn't know what's going on that first night at Bungalow 8 when, under the influence, she insinuates herself into the arms of a Brit golden boy and wakes up in his Pratesi sheets. Nor does she get it when her boss is thrilled that a gossip columnist makes mention of the coupling. Everyone Worth Knowing is Bette's education in the wicked, wicked ways of the velvet rope and red-carpet crowd as Weisberger gives us an amusing if naively earnest tour of Manhattan after dark.
