Paul Cameron is an English literature teacher at a local college and seems to be living a relatively content but somewhat lonely life in his trailer off Mulholland Drive overlooking Los Angeles in a not-too-distant future where man is preparing to launch a big terraforming mission to Mars. But all is not right with Paul. You see, he hears voices. These voices are telepathic communications between alien beings who have inhabited the bodies of people and are planning an invasion. Can Paul discover whose bodies these aliens inhabit and stop them before before mankind is doomed? - Summary by Ben Tucker
