How Life Really Works

Eleanor O'Donnell is completely normal. Mediocre, even. She has a few friends, but she's not overly popular. Her parents are in love and they both work, but they're far from rich. She takes two honors classes in her junior year of high school, but she's not overly smart.
Her best friend, Jasper Crouch, has had a rivalry with a boy named Oliver Ceyton since before she even moved to Georgia in seventh grade. She's always finding them arguing somewhere around; school, restaurants, the grocery store. They've never explained their rivalry, and soon she gave up asking. But one time after arguing, Oliver caught up with Eleanor while Jasper wasn't around and hinted that the arguments and occasional fist fights weren't his fault.
Don't get me wrong, there's no love lost between Oliver and Eleanor, but as she gets closer to finally unraveling the mysterious rivalry between her best friend and his worst enemy, she feels herself drifting away from her best friend, and trusting Oli more and more.
