Brian Harrison wants to keep everyone safe — especially his beloved sub, Jackie Vasquez — and he's convinced the only way to do that is to dig ever deeper in a forbidden investigation. Keeping his activities secret from the State Department means keeping them from his own boss, Luki Vasquez, and keeping secrets from Luki means Jackie can't know either.

Meanwhile, Jackie keeps his own secrets as his kind heart and indomitable spirit drive him to find and help a mysterious homeless woman, who may be connected to a kidnapping. Both men dance around dangers lurking in LA's hidden places.

Love continues to grow, adventurous kink heats up, and a marriage proposal still hangs in the balance. Can a willing shot of trust keep them together and alive when secrets collide?
