Controller Trilogy, Book 1. Once the mutation was recognized, nations raced to identify citizens that carried active copies of the two gene versions, spurring research to insert the genes in more of their populations. One in 10 million has either the aggressive or defensive gene version. Compeller or Immune. Compellers insert thoughts in the minds of Susceptibles if within 75 feet. Those people act on those as if they were theirs, and will do what they are commanded to do. Like soldiers and law officers, some Compellers defend their government leaders, others attack leaders of hostile governments. Immunes are not controllable, and sense thoughts sent to anyone nearby. They are the defenders of a nation's leaders and seek out the foes of their government. Sheldon Stiles is a powerful Controller, the first discovered, a man with two copies of the compel gene, and he's a psychopath. He can make anyone do anything, from robbery, murder, or suicide, and he wants money and power. One Immune stands in his way. Dan Grayson is the first double Immune, and he can sense Compeller thought transmissions and knows who sent them and precisely where they are. He's part of an agency defending US leaders from mind control, but Stiles is out to kill him, his family, and friends. It's personal and deadly. Amid their personal conflict, technology suddenly tips the scale from short-range mental warfare, with the development of amplifiers and transmitters. These allow mass Mind Control of populations of entire cities. Stiles steals the technology, and Grayson is out to stop him. No nation is safe if leaders can be forced to launch nuclear missiles, or armies of their citizen puppets riot, attacking the police and military, who then also join the chaos. The battle has gone global. Free will belongs to those that can take yours from you.
