The Blackhawk Security series follows operatives at a private security firm as they handle dangerous cases and find unexpected romance. The series shares the same world as Trident Security, with former military heroes and high-stakes situations.
The seven books were published between 2018 and 2025. Like most of Cole’s work, the series blends romantic suspense with military and law enforcement themes.
