Obviously the other reviewer was expecting something totally different than what he got...which rather confuses me because while Dean Koontz is usually shelved in the horror section of book stores, his books are often only partly horror. The fact he picked the book up simply being an animal lover shows that he barely gave this book a chance in my opinion.
While not one of the more supernaturally involved books of Dean's, it is a great and twisty thriller, tying together many seemingly unconnectable people together into a life or death situation, along the way revealing hidden secrets and histories and atrocities (what happens to the main character alone is one of the more shocking things I've ever read in a Koontz book) and finding out along the way that all animals are precious and very special in their own ways.
He also manages to tie in quite a few gunfights as well and much backstabbing and double crossing between multiple bad guys (more so than The Husband had) and keeps you wondering exactly what will happen to everyone, and the end has a pretty interesting twist that will make most readers question their own humanity...or make you do what the other reviewer did...I suggest the close minded stay far away from this book.
While I much prefer his more supernatural other worldly books and planet wide catastrophes, this book is a very good read and will keep you very enthralled from beginning to end. If this is your first Koontz book, keep in mind a lot of his books are a lot weirder than this one :)
