Frankenstein: Lost Souls, by Dean Koontz. Unabridged Audio.
This is the 4th book in Koontz's modern take on the Frankenstein mythos -- which is a little confusing, considering how the 3rd book ended. Suffice it to say that there are clones involved, so Koontz was able to extend the tale beyond what sure seemed to be a conclusion.
Two years have passed since the events of book 3, and many of the characters have tried to move on. But when replicants (of a slightly different nature) appear, Detectives Carson O’Connor and Michael Maddison, Erika 5 and Jocko, and Victor’s first creation, the tormented Deucalion, all jump into action to stop the plan. There are some truly Koontz-worthy horror moments, but also some subtle emotions appear, and these moments are a welcome respite from the suspenseful main thrusts of the story.
I like the basic nature of the plot -- that the replicants are starting small, with a small town in Montana, from which they plan to slowly "roll out" their takeover plans. This makes sense, but is a plan that most villains don't seem to think of. The book ends without an ending, and so book 5 has been added to my "to-read" list.
