Aspen Kirkland is a slut. Or at least, that's what she's spent all of high school believing. So when she goes to visit her estranged father the summer after graduation, she has no reason to believe things will change. But then she finds her childhood best friend Sean again, and everything changes. Sean is smart, driven and Harvard-bound: everything Aspen isn't. But the more time she spends with him, the more she feels their old connection. He makes her feel like the person she was before high school, before her life did a 180. But Aspen doesn't want to change, and she doesn't want to make any more mistakes. Between her renewed friendship with Sean, a cute local boy and the revelation that her father may not be as clueless as she once thought, Aspen feels the ground shifting beneath her every day. As the summer unfolds, she finds herself working to reconcile her past, present and future, and carve out a place in her constantly changing universe to call home.
