I enjoyed this book by Koontz, but only gave it 3 stars as, while very exciting and suspenceful in places, I found its length made it feel tedious in places and I was quite sick of the story by the end. Also, while I loved the hero's of the book (Spencer, Valerie and of course Rocky), I didnt think the villians were up to the usual Koontz standard. Eve had very good potential but sadly her charcater was underdeveloped, despite the 720 page length. I also felt the character of the black policeman (I just finished the book and dont remember this name..) was totally unnecesary and seemed to be added two thirds of the way through for no reason at all.
The books starts out very good with many twists as Spencer Grant - accompanied by his dog, Rocky - go in search of a mysterious woman named Valerie Keene, who Spencer met at a bar and instantly took a great attraction to - both her looks and her personality.
A sociopath called Frank, who works for the government is after Valerie - and now Spencer - for reasons that we do not yet know.
Very good if you are new to Koontz, although could be very sameish if you have read his books before as it is very similar to several of his others.
