City of Night - Dean R Koontz

They are nearly indestructable. They are stronger, heal faster, and think faster than any humans ever created – and they must be destroyed. But not even Victor Helios – once Frankenstein – can stop the engineered killers he’s set loose on a reign of terror through modern-day New Orleans. Now the only hope rests in a one-time ‘monster’ and his all-too-human partners, Detectives Carson O’Connor and Michael Maddison. Deucalion’s centuries-old history began as Victor’s first and failed attempt to build the perfect human – and it is fated to end in the ultimate confrontation between a damned creature and his mad creator.
