Review: Each day, sixth-grader Rusty feeds a dog that's left chained in the frigid weather with no shelter, food, or water. When he realizes the dog has been injured, he tries to have Animal Control help - but when that fails, Rusty and his friend Andrew unchain the dog and take it. With the dog in their hideout, the boys face multiple challenges, including Andrew's snoopy sister and the escalating threats of the dog's abusive owner. Even more challenging? The appearance of a ghost dog that appears in Rusty's room and is trying to lead him to an even deeper secret.
