In the Darkest Evening of the Year the plot lines seemed at times to cross and connect in slightly improbable ways, but Koontz was Koontz and carried a slightly fantastic story to the end with believability. (Or maybe I'm just gullible, I'm not sure).
In order to have contrast to the protagonist's "Golden Heart" which was the name of her rescue organization as well as a symbol of her goodness, the bad guys were incredibly bad, indulging in arson, murder, torture and child abuse.
This was a little hard to stomach, but it made me ache even more for goodness to win out.
All in all, I enjoyed this book very much and would definitely reccomend it. Especially if you are a Dean Koontz kind of person.
I think this book was inspired somewhat because Koontz's own dog Trixie, who has graced the back covers of many of his books, and is even credited for writing her own book (with his help of course), passed away last year.
I was sorry to hear that.
Let me add that my favorite Koontz' of all time are Watchers (another one where a dog is the main character) and Odd Thomas.
