"Caravel has seen them - For him it began one lost night on a lonely country road, looking for a short-cut that he never found. It began with a closed deserted diner...and a man too long without sleep to continue his journey. It began with the landing of a craft from another galaxy. Now, Caravel knows the Invaders are here, that they have taken human form. Somehow he must convince a disbelieving world that the nightmare has already begun."
