Out of Time by David Klass is an environmental thriller.
Green Man is a terrorist who is committing acts in the name of waking people up to climate change and the fact that soon it will be too late to make the changes that may keep the Earth inhabitable.
Each target is a threat to the environment. Once the attack happens a letter is sent to the media explaining why that industry must change.
Tom Smith is a young FBI agent who finds patterns. He is assigned to the task force searching for Green Man.
This is a great thriller. Klass has written a fast-paced ride.
