What will happen to humanity if global warming and pollution take their toll on the Earth? Bestselling children's author Patrick Carman's Elyon latest set of books explore that very idea. Atherton: The House of Power, aimed at middle-grade readers, is the latest sci-fi series set after humanity has all but destroyed itself. Like Lois Lowry's The Giver and its companion book, Scott Westerfeld's Uglies trilogy, and Jeanne DuPrau's Ember series, Carman's world of Atherton is a near-future society carefully manufactured to prevent humanity from repeating its past mistakes, and the series explores what happens when the utopia is exposed as a dystopia.

In Carman's universe, Earth, here known as "The Dark Planet", can no longer support life. Atherton is a man-made satellite planet, shaped like a child's top, consisting of three levels: the seemingly uninhabited Flatlands, the agricultural Tabletops, and the lush, wealthy Highlands. Edgar is a boy who works and lives in the fig grove in Tabletops, whose crops go to support the Highlands, where the powerful live in relative luxury while they control the water supply. Edgar, however, is an excellent climber, and uses his talent to span the three levels of Atherton. Soon, he and the other citizens of Atherton realize their worlds are about to collide when the Highlands start to sink into Tabletops.

Carman uses Atherton to explore the ideas of class struggle, limited natural resources, and the value of our environment. Edgar, and his female companion Isabel, are empowering characters that are brave and cunning, and readers will cheer their efforts to find the truth and save their people. Even as an adult, I was drawn into Carman's world, and children will be able to find multiple parallels to our own world (although adults won't have to work very hard.) The mysterious nature of Atherton's past and future will keep readers' interest until the last pages.

Also appealing about the Atherton series is the potentially-vast interactive supplemental material online. Web-savvy kids will have diagrams, video, audio, additional text, and the like to tide them over until the next Atherton book is released. The hardcover release of Atherton: The House of Power will include a free DVD with bonus materials.

For parents looking for engaging, action-packed books that explore environmental themes in an approachable manner, Atherton: The House of Power is well worth a trip to your local bookstore when it is released on April 3rd.
