The True Blue K-9 Unit series follows eleven stories of K-9 teams and their handlers. Justice Mission, Act of Valor, Blind Trust, and the other entries trace interconnected investigations, published primarily in 2019 with the Brooklyn Christmas entry extending into 2020.
The series title’s emphasis on “True Blue” loyalty applies equally to the dogs and their human partners, with both proving their dedication under pressure.
