Lissy Jablonski was fifteen during the summer of 1985. That was the summer her father, a soft-spoken gynecologist, up and left her mother for a redheaded bank teller. The same summer Lissy and her mother disappeared from their quiet New Hampshire lives to have an adventure of their own amid a cast of unlikely characters, including a Valium-addicted ex-debutante and a suspected mobster. The summer the reliably comforting "girl talks" with her mother began to reveal startling secrets.

Now an almost-thirty-year-old advertising executive in Manhattan, faced with her father's imminent death and newly pregnant by her married ex-lover, an unmoored Lissy finds herself looking back across the years. Contending with her affections for an old flame and his doomed marriage to a Korean stripper named Kitty Hawk, as well as the tangible legacies of that unmentionable summer with her mother, she realizes that she has become more like her mother than she ever could have imagined.
