After attempting to sever all ties to her life as a hired assassin, a woman struggles to understand who she has become. She knows she doesn’t want to kill again --- but it proves to be a difficult habit to break. Adrift and disconnected, she meets an old woman: Imogen O’Brien, a world-famous artist who has spent the last three decades living a hermit-like existence on a rustic desert estate in a national forest. Imogen invites her to stay and work for her, offering mentorship in return as the woman deepens her own interest in art. What quickly becomes apparent is that elements of Imogen’s past are shrouded in danger, sorrow and darkness. Rather than growing as an artist, the former hitwoman soon finds herself enmeshed in a dangerous mystery with strands that stretch decades into the past.

Taking lives has taken its toll. Her moral justifications have faltered. Do any of the people she has killed --- some of them heinous, but all of them human --- deserve to die? Her next target is Cameron Walker, a rancher in Arizona. When she arrives at his remote desert estate to carry out her orders, she discovers that he is a kind and beautiful man. After a lengthy tour of the ranch, not only has she not killed him --- she’s wondering who might want him dead. She procrastinates, instead growing closer to Cameron. She learns that he is passionate about wild horses and has been fighting a losing political battle to save mustangs that live on protected land near his ranch --- he’s even received death threats from his opponents. Suddenly, she’s faced with protecting the man she was sent to kill.

Her assignments were always to kill someone. That’s what a hitman --- or hitwoman --- is paid to do, and that is what she does. Then comes a surprise assignment --- keep someone alive. She is hired to protect Virginia Martin, the stunning and brilliant chief technology officer of a hot startup with an environmentally important innovation that will change the world. She’s confused about the “why” of her new commission, but she addresses it with her usual skill and stealth, determined to keep the young CTO alive against the ever-increasing odds. The spirit of an assassin --- and her nameless dog --- permeates this struggle to help a young woman as powerful forces mount against her.

What would it take for you to kill someone for money? And if you did, who --- or what --- would you have become? These are the questions one woman faces when she loses everyone she loves and everything she has. When the opportunity arrives to reinvent herself as a killer for hire, she takes it. She’s good at it --- and if she doesn’t do it, someone else will. Then everything changes when she learns about a serial killer so horrible she vows to find him and kill him until --- overcome by self-doubt --- she seeks redemption rather than vengeance.
