Frankenstein: The Dead Town is apparently the last in the Frankenstein series by Koontz. I only say apparently because I thought it was over once and, like the original monster, the series keeps coming back from the dead. This is a great retelling of Frankenstein. Koontz can elicit a spine chill like nobody else, and there are plenty of them in this book.
The chaos in Rainbow Falls, that started in Lost Souls, continues with more replicantes and more builders that can't be stopped. But something is starting to unravel and there's hope. The question is, will Deucalion be able to find Victor in time? Very highly recommended.
