Novels

His 1994 book California Blue gathered very positive reviews for its quiet yet compelling treatment of environmental issues. In 2001 Klass published You don’t know me, which uses an edgy first-person narrative to tell the story of a teenage boy’s life with an abusive stepfather-to-be. The book has been published in 18 languages, was named an ALA Best Book For Young Adults, and continues to be popular with young adult audiences in the United States and internationally.

Firestorm is the first book of the Caretaker Trilogy, a series of science fiction thrillers with an ecological theme. Firestorm was the first book ever endorsed by Greenpeace and was praised by critics for its combination of entertainment value and environmental message, garnering an American Library Association (ALA) Best Book citation, a starred review from Publishers Weekly, and a favorable review by The New York Times Book Review. The story focuses on Jack Danielson, a teenager sent back from the future to save the world’s oceans.

Whirlwind, the second book in the Caretaker Trilogy, tells the story of Jack’s efforts to save the Amazon rain forest; published in March 2008 by Farrar, Straus and Giroux. The third book in the trilogy is Timelock, published in fall 2009.
