I used to enjoy Dean Koontz's books - his earlier works are very good. I grew tired of the formulaic plots of his later books though, and stopped reading them.
Also, why does he always name the protagonist's son/adopted son "Colin"?
The absolute WORST Dean Koontz book I ever read was "From the Corner of His Eye" - a total pile of crap. I was so disgusted with the book when I finished it (yes, I read it to its sorry end, desperately hoping it would improve) I wanted to go back to the bookstore where I bought it and demand a refund.
Sorry about the rant Roland! I couldn't help it. Long days and pleasant nights!
