Subconscious torture for political and corporate subversion. That's the trade of Vathos--creeping into a target's dreams to force the shady ends of their clients. It's a dirty business. Vangelis Zervas is one of their Subversion agents and makes a living inflicting pain on people in their sleep. A recipient of the most stringent training and a man of few qualms, he'll do whatever it takes to get the job done. But a series of events calls his dedication into question when strange things begin to happen as he is infiltrating the dreams of his targets. Soon he's asking himself--is it he in the mark's head, or is someone else in his? A no-holds-barred dystopian horror that will put your teeth on edge. * Cerebrum is the first installment in Ultan Banan's 'Sistema Series'.
