Will Parker and his friends have made it to the White Mountains and the resistance group that lives there. In this future Earth where the Tripods now dominate. Will with two others are chosen to compete in the annual games in Germany. Three winners are taken into the Tripod city. Will with his friend Beanpole and Fritz travel to compete. Will and Fritz are two of the winners and are taken into the city. There they are assigned as personal slaves to a Tripod. The aliens are reveled to be huge reptiles. The high gravity environment ensures that the human slaves will only last for two to four years. While Fritz gets a master that likes to torture him, Will gets a kind master. The Tripod treats him like his dog. As his slave he finds out the history of how the Tripods conquered Earth. He also finds out that they plan to terraform the Earth in four years. Soon humanity and all life will be extinct. So now Will and his companion Fritz must escape the city to warn the resistance.
The second book in the trilogy gives us a look at the Tripods. Who they are and why they conquered Earth. They also give us a brief history of how they conquered the Earth. Seems they used TV signals to brainwash enough people to help them take over. Kind of an amusing idea. I always found this such a creepy book in how they have so successfully gained control of the minds of humans. The slaves are totally devoted to their masters and will actually go to The Place of Happy Release when they feel they can no longer serve their masters. The Place of Happy Release is where they kill and dispose of the slaves. I found it an interesting and unique idea to have the aliens conquer and control us my using mind control. The second in the trilogy is the best of the books. It was enjoyable, exciting and established the approaching threat to Earth.
