Caleb Tanner is a unique combination of both killer and savior all wrapped into one. As a former Navy Seal and medic, Caleb has the ability to both take life and restore it with ease, making him a vital member of Bravo Team at Knight Security. He would kill or be killed for his teammates and the women they love, earning him the reputation of both fearsome warrior and compassionate caregiver. When a new job assignment flares every protective instinct within Caleb, he is fully prepared to step in as a knight in shining armor, but what if his new assignment, Elaina Flores, has no interest in being saved?

As the leader of Knight Security and the handler of all four special operative teams, Hunter Hall's life revolved around bringing order to a world of chaos.
