Into sci fi or fantasy? Of a good, fast-paced read? Try Atherton: The House of Power by Patrick Carman. Atherton is the story of a boy named Edgar who lives on a planet that was created because the Earth is dying from pollution. Atherton is a world geographically divided into three tiers, where the elite at the top live off the work done by the people that live down below. Edgar is a farmer on the middle level and decides one day to climb up to the top level and discover what it is like to live on top.
But Atherton isn’t a safe place to live either. The three levels are starting to fall into each other and all people are in danger of being eaten by the scavengers living at the very bottom. Check out the Hungry City Chronicles by Philip Reeve for more exciting dystopia reads.
