Unbonded wolves are unsafe—something Rainer "Rain" DuBois knows all too well. As a former leader of the Black Wolf Rangers, it's his job to find them, protecting packs from all over the country. With a mission to lead a team of enforcers into the heart of Mexico to face off against a madman, nothing can derail him from his goal.

Until he meets Nora Cavanaugh...

Teaming up with Rain is just what Nora needs to escape her relentless and unforgiving family's grip. Always forced to walk the line, Nora craves a little rule-breaking of her own. But working with Rain ignites a magick that Nora thought fizzled out long ago. Giving in to that pull, that familiar and hot sensation, just might put them in more danger than they ever imagined.
