Frankenstein Lost Souls - Dean Koontz (2010)

The war against humanity has begun. In the dead hours of the night, a stranger enters the home of the mayor of Rainbow Falls, Montana. The stranger is in the vanguard of a wave of intruders who will invade other homes... offices...every local institution, assuming the identities and the lives of those they have been engineered to replace. Before the sun rises, the town will be under full assault, the opening objective in the new Victor Frankenstein's trajectory of ultimate destruction. Deucalion - Victor's first, haunted creation - saw his maker die in New Orleans two years earlier. Yet an unshakable intuition tells him that Victor lives - and is at work again. Within hours Deucalion will come together with his old allies, detectives Carson O'Connor and Michael Maddison, and Victor's engineered wife, Erika Five, and her companion Jocko to confront new peril. Others will gather around them. But this time Victor has a mysterious, powerful new backer, and he and his army are more formidable, their means and intentions infinitely more deadly, than ever before.
