Thinking that the series ended with the last book, I was surprised to see Frankenstein: Lost Souls. Having enjoyed the last three (the first two more than the last), I figured what did I have to lose?

In this book, we rejoin the primary heroes (or more aptly survivors) from the first trilogy. Two years have passed since the last book, and everyone has moved on in their own, unique way. The characters have changed, and Koontz tries to show that they have grown. In general, he succeeds. We get to see glimpses of Victor (the clone we met in the last book), who is definitely different (and I think slightly more scary).

We also get to meet a lot of new characters. Some are better than others. I liked Nummy and Mr. Lyss, who are more developed and have more screen time. The FBI agents were less so, and seemed much more one dimensional. The old western author and the 9 year old were somewhere in between.

The plot is fairly straightforward, and honestly not much to write home about. It is basically the same as the previous three, only set in small town Montana.

My primary issue is that Koontz has several plot lines obviously going to collide eventually, but he never gets around to it. I'd rather that he put the next book in with this one and made it more complete than leave it the way it is. Honestly, the book isn't that long, so I don't know why they have divided it up into (at least) two books. I am assuming that they are going to make this another trilogy, but I don't know that for certain. Call it my intuition.

Overall, the book was OK. If you liked the first three, this is more of the same. If you didn't like the first three, this is more of the same. If you didn't read the first three, don't worry, you can pick this one up and still get it.
