A Big Little Life is a wonderful book, as I'm sure you know. I have some Koontz books on my Kindle, all of the Odd Thomas ones and some more recent. I was at the Books A Million here in little Vero Beach, FL and found a signed copy of The City (his newest) on the shelf at cover price, so I of course had to pick it up. Haven't read it yet, though, but I enjoyed Innocence!
In fact Books A Million still offers autographed copies of The City (and other signed books) on their web site.
