In the near-future USA, a one-child policy is ruthlessly enforced. Everyone follows the Rule of One. But Ava Goodwin, girl of the top of the Tx Family Planning Department, has a magic formula—one her mom died to maintain and her father has helped to cover up for her entire life.

She has the same twin sister, Mira.

For eighteen years Ava and Mira have lived as one, trading places day after day, maintaining an compatible existence right down to the most telling detail. However when their charade is certainly exposed, their most severe nightmare begins. Right now they must keep behind the father they like and fight for his or her lives.
