Grace Bradshaw knows the exact minute she will die. On death row for murdering her infant son, her last breath will be taken on February 15 at 12:01 a.m. Eleven years, five months, and twenty-seven days separate her from the last time she heard her precious daughter's voice and the final moment she'd heard anyone call her Mom. Out of appeals, she can focus on only one thing - reconnecting with her daughter and making sure she knows the truth.

Secrets lurk behind Sophie Logan's big house and even bigger bank account. Every day when she kisses her husband good-bye, she worries her fabricated life is about to come crumbling down. No one knows the unforgivable things her mother did to tear her family apart - not her husband, who is a prominent plastic surgeon, or her synthetic friends who live in her upscale neighborhood.

Grace's looming execution date forces Sophie to revisit the traumatic events that haunted her childhood. When she returns to her hometown, she discovers new evidence about her baby brother William's death seventeen years ago - proof that might set her mother free but shatter her marriage forever.

Sophie must quickly decide if her mother is the monster the prosecutor made her out to be or the loving mother she remembers - before their time runs out.
