Parks’s home is his refuge, his cosmos of resources and headquarters for his powerful analytical skill. His chauffeur, Jacob, is a capable and trustworthy partner.

The price of ending this reign of terror may be too much for mere humans to pay. Parks’s battle against evil reveals the hazards of confronting the unknown and the severe consequences of facing the forces of hate and perverse genius.
