It has been quite a while since I've read one of his. He was getting a bit too formulaic for my taste, after Intensity, which was the last really good Koontz novel I read, in particular. Dark Rivers Of The Heart is a great novel; all of Koontz's skills and unique strengths are on display in that one. In my estimation, it's his either his best book or close to it. Lightning is good, as are Twilight Eyes, Strangers, Night Chills; in general, his late '70s-mid '90s output was pretty good. I basically stopped reading his new work around the turn of the century; I don't remember what was the last Koontz novel I read new, only that it was at least 6 years ago.
