The Nanny Diaries is an absolutely addictive peek into the utterly weird world of child-rearing in the upper reaches of Manhattan's social strata. Co-written by two former nannies, Emma McLaughlin and Nicola Kraus, the novel follows the adventures of the aptly named Nan as she negotiates the Byzantine byways of working for Mrs. X, a Park Avenue mommy. Nan's 4-year-old charge, the hilariously named Grayer (his pals include Josephina, Christabelle, Brandford, and Darwin) is a genuinely good sort. He can't help it if his mother has scheduled him for every activity known to the Upper East Side, including ice skating, French lessons, and a Mommy and Me group largely attended by nannies.
