Interesting premise. Not quite the "edge of the seat" as Koontz's, 'Watchers', but well worth the read.
This was an all right book - it certainly wasn't great, but it wasn't terrible either. It was well-plotted and rather unpredictable, but the action was slow-paced, the characters were stuff and unrealistic and the writing was average at best. Still, it was a solid premise - and, really, who can resist a dog story?
