Jeneration X: One Reluctant Adult's Attempt to Unarrest Her Arrested Development; Or, Why It's Never Too Late for Her Dumb Ass to Learn Why Froot Loops Are Not for Dinner

In Such a Pretty Fat, Jen Lancaster learned how to come to terms with her body. In My Fair Lazy, she expanded her mind. Now, the New York Times best-selling author gives herself - and her generation - a kick in the X, by facing her greatest challenge to date: acting her age.

Jen is finally ready to put away childish things (except her Barbie Styling Head, of course) and embrace the investment-making, mortgage-carrying, life insurance-having adult she's become.

From getting a mammogram to volunteering at a halfway house, she tackles the grown-up activities she's resisted for years, and with each rite of passage she completes, she'll uncover a valuable - and probably humiliating - life lesson that will ease her path to full-fledged, if reluctant, adult.
