Six years ago, her husband, Randy, was unmasked as a serial killer and is on death row. Her past catches up with her when Charles Pritchett, the father of one of Randy's victims, outs her as Randy's ex-wife.

Unfortunately, the discovery of Nina and Hayden's whereabouts is news to Randy and possibly a copycat killer, putting their lives in danger. In The Killer's Wife, the reader gets an unique view through Nina's eyes of her discovery of Randy's evil nature. A quick, fast-paced read.
