Jack Danielson is a normal high school senior when his father reveals that him and his mother are not his true parents and that Jack must run away. After being attacked by bat-like creatures and shot at by lasers, Jack realizes that things are more dangerous than he first believed. He eventually discovers that he has been sent back 1000 years from the future to stop the environmental disasters that are destroying the future world. Lots of action, some good fight and chase scenes. This it the fire book of the Caretaker Trilogy. Firestorm is supposedly going to be made into a movie by Warner Bros. (and Klass was the screen writer for Desperate Measures and Walking Tall.)
