If Kate were Lady Brett Ashley, the devastating heroine of Hemingway's The Sun Also Rises, she'd spend her summers careering around the Riviera in her coupe, breaking hearts by the dozen--because why not? In reality, Kate's never even had a boyfriend, and she'll be spending the summer abetting her mom's lame ploy to make her dad jealous: running off to Cape Cod and crashing at the seaside home of her wealthy friends, the Cooper-Melnicks. To add to the shame, the Cooper-Melnicks' gorgeous daughter Sarah is a bit like Lady Brett, and she seems less than thrilled to hang out with her new houseguest. Any dreams Kate once had of a perfect summer are ruined.

That is, until Sarah's cute, witty friend Adam starts drawing Kate into the fold--and seems intrigued. With Adam around, Kate feels like she just might have a bit of heartbreaker potential after all. But when a breezy summer romance quickly grows more complicated can Kate keep pretending her relationship with Adam is just a carefree fling? Or will she take the risk and tell him her real feelings? Suddenly Kate is asking herself a question she never thought she'd stoop to: Is she girlfriend material?
