In Valerie Frankel's clever, charming novel, a single woman in her early thirties discovers the insecurities of sibling rivalry are as strong as ever when she gets stuck living and working with her sister again.

Let the sibling rivalry begin...!

Meet Francesca Greenfield, a smart, urban professional tossed out of her so-so career and into the business of selling coffee alongside her pretty, perky sister Amanda.

Francesca has always known that she was the smart sister." Amanda was soft and lovely from the beginning and had always garnered most of the attention--and all of the dates. Now they've been thrown together in a last-ditch effort to save the family business before it goes permanently down the drain. As for the coffeehouse itself, well, there's rarely a dull moment. And who can forget about love? Or at least sex. Thanks to a promotional contest, it's not long before Amanda is looking to explore the aura of a buff mountain climber while Francesca considers shedding more than her inhibitions with a J. Crew model.

The stakes are rising. It's time to find out if smart or pretty knows best, whether the distinction really suits either one of them, and if the Greenfield sisters can actually live happily ever after.
