Skyjack

From publisher blurb: Is it nature or nurture that turns a guy into a criminal? Jack saw his dad as a hero until the day he disappeared while on a casual flight. With no one to serve as a moral compass, Jack flew toward the wrong crowd. Training, tech, and bad intentions later, Jack had become a pirate of the airways, looking for his next big score. Can your heroes take on on scourge of the sky known as, SKYJACK?
