Query: Shattered Expectations

This was the first Koontz book I have read and was somewhat disappointed. I did enjoy the rising tension as an unknown person was following Alex and Colin. And the feeling of rejection Alex experienced was an interesting tactic by the author. But there were unresolved subplots, and the ending was somewhat abrupt and predictable. I'll probably read another Koontz book but will seek recommendations first.
