Under the blazing cover of a post-nuclear, technology-crippled world, Sarah Coolidge is an expert at being neither seen nor heard.
She was an afterthought to her abusive parents.
She's invisible to the criminals she works with.
And she'll soon be the death-dealing ghost her enemies never see coming—if she can just shake loose the one person who does see her.
The one who could ruin her.
The one who gives her a reason to live.
