Sara B. is losing her cool.Not just in the momentary-meltdown kind of way—though there's that, too. At the helm of must-read Snap magazine, veteran style guru Sara B. has had the job—and joy—for the past fifteen years of eviscerating the city's fashion victims in her legendary DOs and DON'Ts photo spread.But now on the unhip edge of forty, with ambitious hipster kids reinventing the style world, Sara's being spit out like an old Polaroid picture: blurry, undeveloped and obsolete.Fueled by alcohol, nicotine and self-loathing, Sara launches into a cringeworthy but often comic series of blowups—personal, professional and private—that culminate in an epiphany. That she, the arbiter of taste, has made her living by cutting people down...and somehow she's got to make amends.
