Meet Rose Feller, a thirty-year-old high-powered attorney with a secret passion for romance novels. She has an exercise regime she's going to start next week, and she dreams of a man who will slide off her glasses, gaze into her eyes, and tell her she's beautiful. She also dreams of getting her fantastically screwed-up, semi-employed little sister to straighten up and fly right.

Meet Rose's sister, Maggie. Twenty-eight years old and drop-dead gorgeous. Although her big-screen stardom hasn't progressed past her left hip's appearance in a Will Smith video, Maggie dreams of fame and fortune -- and of getting her big sister on a skin-care regimen.

These two women, who claim to have nothing in common but a childhood tragedy, DNA, and the same size feet, are about to learn that they're more alike than they'd ever imagined. Along the way, they'll encounter a diverse cast of characters -- from a stepmother who's into recreational Botox to a disdainful pug with no name. They'll borrow shoes and clothes and boyfriends, and eventually make peace with their most intimate enemies -- each other.
