Going Dark by James W. Hall
Thorn, the private investigator from previous James W. Hall novels, likes his privacy and lives a very primitive lifestyle on his own little piece of land in the Florida Keys. He spends his days making fishing ties and minding his business. But, soon Thorn is rousted from his simple life by some troubling news.
When Thorn finds out that a longtime friend of his has been killed by a crocodile while doing the job that she loves, he is automatically suspicious of her death and starts looking into things. Leslie was way too good to allow something like this to happen. During his investigation, Thorn and his newly discovered son, Flynn, get mixed up with a group of environmental activists intent on shutting down the largest nuclear power plant in Florida. What starts out as a nonviolent plan turns deadly when some of the members show that they have their own agenda and nothing is going to get in their way.
