MrFrosty

Lucas "Luke" Callahan has spent his life walking the thin blue line between order and chaos. As a decorated K9 officer and former Army MP, he’s seen the worst the world has to offer—but he never faces it alone. His partner, Ghost, a fiercely intelligent Belgian Malinois, is more than just a police dog. He’s Luke’s shadow, his shield, and the only one who truly understands the weight he carries.

When a routine call turns into a deadly ambush, Luke and Ghost find themselves entangled in a dangerous conspiracy that stretches deep into the criminal underworld. As they hunt for answers, old wounds resurface—ghosts of the past Luke thought he had buried. With every step closer to the truth, the stakes rise, putting not only their lives on the line but also those of the people Luke swore to protect—including his wife, Isabella.

Outnumbered and outgunned, Luke and Ghost must rely on their unbreakable bond to survive. But in a world where loyalty is rare and justice is never guaranteed, one question remains:

How far will a guardian go to protect his own?
