Adult college student Leslie, a sexy and athletic blond with an adventurous, even rebellious streak, not to mention a liberal—even sordid—sexual history, has everything going for her. She has a satisfying job with an understanding boss, a rewarding college career, plenty of friends, and a loving—if slightly unconventional—family. When her father decides to remarry not long after she moves out of the house, her new stepmother brings with her a son of her own, Peter—a man of remarkably similar interests who appears to be at a similar point in his life to that of Leslie's own. The two of them rapidly become friends, and then become inseparable, as their social circles merge, and it's quickly apparent to both of them—Leslie in particular—that it's love at first sight, but Leslie has no idea how to tell her father—or her stepmother—about their relationship. When Leslie becomes unexpectedly pregnant a few years after they start having regular sex together, she has no idea how Peter is going to react to the news, what he's going to feel about the state of her pregnant body... or what secrets he might be hiding in his past, about which she had no idea whatsoever.
