Query: Disappointed

I'm a fan of Dean Koontz, but this is definitely not one of his better works. The dialogue is artificial and hokey, and I actually found myself rolling my eyes during Dan's conversations with his colleagues. The story was predictable and slow. I usually pass good books on to friends and family, but I am not recommending this one to anyone I know. Don't give up on Dean Koontz if this is the first book you've read by him. Read The Bad Place, it is absolutely fascinating. Also recommended: Midnight and Lightning. I guess you can't win them all. Pass this one up and read his other books instead.
