Warner Bros. Pictures has picked up the rights to the teen sci-fi action, Firestorm.

The film is based on the first book of the David Klass Caretaker Trilogy. Variety notes the books revolve around a seemingly normal high school senior who finds himself at the center of an epic battle that's being fought both now and a thousand years in the future. The fate of Earth hangs in the balance.

The series has an underlying environmental theme, and Firestorm became the first novel to be endorsed by Greenpeace. Warner also has the rights to option the two additional books in the series, the second, Whirlwind, will focus on rainforests, while the third, Timelock, will address global warming.

No production schedule has been set for Firestorm.
