Lively young socialite Nancy Carrington-Chambers has always believed an excellent sense of style and strict attention to detail are what it takes to succeed, but her own husband Todd is showing symptoms of incurable tackiness, so Nancy flees their McMansion for her posh San Francisco apartment. She knows her event planning company, Froth, is a real winner, but she must prove herself by reinventing the turgid Barbary Coast Historical Museum fundraiser. Luckily, Nancy now has the perfect assistant. Derek Cathcart is British, impeccably dressed, gorgeous, and clearly gay—so why does Nancy find him so attractive?

Before Nancy can unravel her feelings, her irresponsible cousin Birdie abandons her little daughter with Nancy and takes off. Nancy, Derek, and Eugenia make an unlikely “family,” but strangely it seems incredibly right. Now Nancy’s parents are pressuring her to return to Todd, and she still has to pull off a spectacular party. For someone who’s always known exactly where she’s going, Nancy is in dangerously uncharted waters.

Irresistibly funny and romantic, Nancy’s Theory of Style shows that happiness and love—just like fashion—aren’t about playing it safe.
