The guiltiest people aren't always the ones behind bars. As a new nurse practitioner at a maximum-security prison, Brooke Sullivan is taught three crucial rules: Treat all prisoners with respect. Never reveal any personal information. Never EVER become too friendly with the inmates.

But nobody knows that Brooke has already broken the rules. Nobody knows about her intimate connection to Shane Nelson, one of the penitentiary's most notorious and dangerous inmates. They certainly don't know that Shane was Brooke's high school sweetheart—the star quarterback, the golden boy who's serving a life sentence for a series of grisly murders.

Or that Brooke's testimony was what put him there. But Shane knows. He knows more than anyone.

And he will never forget.
