Judy Webster is born in a mud-splattered tent at Woodstock, just as Crosby, Stills, and Nash take the stage. Her mother, Cassie, is a beautiful, flawed flower-child who brings her little girl to anti-war protests and parties rather than enroll her in pre-school. But as Cassie's husband, Kirk, gradually abandons '60s ideals in favor of a steady home and a law degree, their once idyllic marriage crumbles.

Dragging Judy back from the Kentucky commune where Cassie has taken her, Kirk files for divorce and is awarded custody. When Cassie eventually moves to an ashram in India, Judy is grief-stricken. At school, she constructs lies to explain her unconventional home-life, trying desperately to fit in to the world her mother rejected.

Cassie calls and writes, occasionally entering Judy's life just long enough to disrupt it. But little by little, Judy is growing up. As she grapples with her father's remarriage and her own reckless urges, she encounters all the joy and heartbreak that goes with first love, first loss, sex, drugs, and self-discovery. And when Cassie comes home again, Judy, who has tried so long to find a place in her mother's life, must finally decide what place Cassie claims in hers. . .
