Ten years ago, Ruby Leander was a scared, runaway 19-year-old who found a baby in an Oklahoma rest stop trash can. Overwhelmed by memories of her own abandonment years earlier, she made a split-second decision to put the baby in her car and keep driving.

Over the years, Ruby and her daughter Lark made a home for themselves in Santa Fe, New Mexico. Lark has grown into a precocious, animal-loving imp, and Ruby has built a family for them around supportive friends and her boyfriend of three years.

Then, when Ruby reads a magazine article about an infant kidnapped by car-jackers, the lie that she created about Lark's origins is shattered. Ruby never dreamed that she had done anything wrong by rescuing an abandoned infant, but now she is forced to make a decision that will change her life, and Lark’s, forever.
