What a wasted opportunity this truly dreadful book is. Weisberger has taken a world rich with comic potential - a world that should have you crying with laughter - and rendered it as sober as an AA meeting. I would hazard a guess that, during her time at Vogue, she did not encounter Ms Wintour's famously ruthless little red pen because the idea of editing out anything - anything - is anathema to her.
