The POW: Book 2 of Hanson's War in Bloomington, MN

In the POW, Book 2, Hanson Series, Their small, independent oil company, Hanson Oil, has made them very wealthy. When the Hansons win a lengthy court battle with the feds and a local jihadist cell targeting the Hanson wealth, the Hanson family, Hoot, once a laid-back oilman, his feisty wife, Hanna, their twin girls, and the best damn bird dog in the state, think their nightmare is over.
Seeking the riches that they have yet to enjoy because of the problems brought by the notoriety of the wildcat strike, the jihadist cell survivors take revenge, killing many of their friends and kidnapping one of the twins.
Hoot and Hanna take the fight to the jihadists, using their Hanson Oil money to form Hanson's Army disguised as a security company known and feared for the white hats they wear.
The bad guys soon learn that the Hansons and their army have no fear, no forgiveness, unlimited resources, and take no prisoners.
