Piper Kennedy (not one of those Kennedys) is a lot of things. She's the one with the longest hair and the best grades. She's the one with the loud laugh and she's the gay guy's best friend but, most of all, she's the class flirt, at least according to everyone in her class and every yearbook since middle school. Piper doesn't mind her reputation though. After all, flirting is harmless and so very entertaining. But most guys seem to be getting intimidated by her eyelash-batting, hair-twirling ways and Piper is finding her senior year somewhat dull without a flirting challenge. Until her second-grade boyfriend Kyle Morgan shows up and threatens to take her title of Biggest Flirt. She can't have that happen, now can she? A girl's gotta fight for what's hers. Even when the enemy looks as incredibly Abercrombie-&-Fitch-Model-Worthy as Kyle Morgan does. Piper was a fool to think her senior year would be dull because by the end she will have encountered a very angry giraffe, an extremely awkward conference with the school's administrative staff and a boat ride with one too many mishaps for someone who hates the water. Flirting is harmless after all, and so very entertaining, right?
