A COMBINATION POLICE PROCEDURAL AND AVIATION THRILLER In this third book of the PISTONS and PROPELLERS series, Collie and Marv are unaware that law enforcement is no longer looking the other way as South Texas pilots run black market consumer goods across the border. SkyDog is almost done with smuggling anyway, they have borrowed money to turn their rough organization into a legitimate aircraft overhaul station by converting surplus military airplanes for civilian use. Money and time are running out and the bank is threatening to freeze all their assets. Things are getting complicated enough, but now Collie's friend David Torres calls in a favor. He wants to rescue a young girl who is being hunted by cartel assassins in Mexico. Collie and David pick up the girl and her aunt from a clandestine airstrip in the middle of the night, not realizing that Air Interdiction is on their trail.
