When Delaney Colt, the top fighter in the Black Lightning pack, is asked to train members of the Dark Thunder pack, she sees it as just another job. She has helped to train many pack allies so the request was nothing new, or so she thought. Little did she know that once she crossed on Dark Thunder territory, her life would forever be changed thanks to the most feared alpha in the country, Jaxon King. Although she had never met him, she knew his reputation. Delaney quickly realizes this job may take a little longer to complete, it may even take her a lifetime.
