Atherton no. 2: rivers of fire (Little, Brown Book Group)

n Book One, the formerly three-tiered world of Atherton began to sink and finally became flat. In Book Two, the process of inversion has begun. The Highlands, the center of Atherton, is sinking; Samuel and Isabel are trying to sneak into The House of Power to restore water to the world of Atherton; and Dr. Kincaid, Vincent and Edgar make their way towards the edge of the Highlands, intent on entering the secret underground refuge of Mead's Hollow and finding the key to unlocking Dr. Harding's brain. They must discover the solution to overcoming the threat of the deadly Cleaners, creatures now unleashed on the flattened land, before it's too late. But Mead's Hollow holds more secrets than any of them had ever imagined
