Every time Hack wrote one of these Junior Ranger books he swore it would be the last one but kids loved them because while their parents thought they were wholesome stories for boys, they were actually packed with scenes of angry anal sex. In this one, a pack of man-eating tigers terrorize Yellowstone Park (Hack is adamant that wild tigers roam Yellowstone Park, despite all evidence to the contrary) and Ranger Joe has to disperse them gently and nonviolently. When he does, a gorgeous heiress who was camping at the park thanks him with a session of angry anal sex.
