Sole Survivor was one of the most suspenseful Koontz books I've read, and I've read them all.
Joe Carpenter's wife and two daughters were killed 1 year ago in an airplane crash. He's quit his job, moved and not given any friends his forwarding address...he's in a deep depression trying to cope with his families demise. That's when something strange starts to happen: people appear to be following him, a bizarre lady is at the graves of his family taking a picture and friends of his are committing suicide for no apparent reason. He's in a race against time to figure out why he's being hunted, what this lady has to tell him and how this relates to the fatal plane crash a year prior.
One reviewer commented that they did not like the character of Joe, that he was whiny and annoying- for me, Joe was a likeable character and well-developed. I think his feelings of loss were realistic- what do you expect after he just lost his entire family- to have moved on in 1 year's time? I thoroughtly enjoyed Joe's ponderings and the deep-thought that was put into this character and his feelings put into words. There were many sentences and paragraphs that I wanted to take a highlighter too, they seemed so profound. I can't say the same for every Koontz book...
I'd recommend this book for Koontz fans. I enjoyed every last bit of this book, up until the ending, which was not as exciting as I expected...but still worthwhile.
