"Cooper's adventures continue as the crew go back to his old city and make a startling discovery. Things in the city were not as he left them nearly a year ago. Also, a mysterious stranger has wandered into the village while Cooper's rescue mission was underway. The boys are in for a few surprises when they return from the old city. The action doesn't stop there. One of the rivers washes down an interesting artifact of unkown origin. In an effort to discover what this object is, Cooper sets out on yet another adventure, but this one will push him to his limits in an environment that most of the surviving humans have never had to endure. In the face of these dangers, with his dogs at his side, Cooper can only do what he is best at, adapt and try to survive." -- Page [4] of cover.
