Former journalist, now mystery writer, Leah Nash receives a heartfelt email from Marianne, a reader she's never met. Marianne's sister Celia is in prison for the murder of her married lover, Eric. She begs Leah to save Celia from serving life for a crime she didn't commit.

However, Leah is pretty sure Celia did kill Eric. The case against her was very strong and the jury delivered the guilty verdict in less than an hour. But Marianne's desperation strikes a chord in Leah due to the guilt she feels over failing to save her own sister.

Peeling back the layers of Eric's life, Leah uncovers multiple suspects who had reasons to want Eric dead. All of them—Eric's wife, sister, a bankrupted neighbor, a political adversary, and a cuckolded husband—are concealing secrets. As Leah navigates a maze of lies and alibis, each clue only deepens the mystery.

Leah becomes so enmeshed in saving Celia that when she begins to receive anonymous messages, she attributes them to a fan with boundary issues. The county sheriff, who happens to be her boyfriend, isn't so sure. But as Leah works to prove Celia's innocence and bring the real killer to light, is a stalker waiting to close in?
