It is the 1960s, in suburban New York City, and twelve-year-old Maggie Scanlan begins to sense that despite the calm surface of her peaceful life, everything is going strangely wrong.

When her all-powerful grandfather is struck down by a stroke, the reverberations affect Maggie's entire family. Her normally dispassionate father breaks down, her mother becomes distant and unavailable, and matters only get worse when her cousin and her best friend start doing things to each other that leave Maggie confused about sex and terrified of sin.

With all of this upheaval, how can she be sure that what she wants is even worth having?
