Emily's Comments: A devastating war has left the world in ruins. Out of the destruction the survivors have created new cities, mobile traction cities that roam the countryside looking for small towns to devour for energy. They call it Municipal Darwinism. In the traction city of London, there is a conspiracy to create a new, extremely powerful weapon that will change the world forever. At the center of the chaos are two teenagers struggling for survival and racing to save the lives of thousands. This is the first in a series that you could definitely become addicted to! I would recommend this book to both adults and teens. Check Status at GPL
