I am a fan of Koontz books, so I am used to the sometimes frantic tempo he can employ in his stories. The Silent Corner was a bit too frantic to keep my interest.  The main character never became sympathetic, I knew too little about her personality, only what was driving her on her quest.  The characters that were introduced to help her along were never fully realized.  They were too fleetingly included, which I realize was done purposely.  The main character, Jane, was supposed to be on her own, on the lam, running from bad guys.  No one was safe, she didn't want to pull anyone into her hunt for "the truth."  The downside to this was never getting attached to any of the characters, I wasn't invested in the plot or in finding out what the "truth" was.  Disappointing, I found myself skimming through chapters to get to the good parts.  

Um, from the first page:

"... I should try not to be so reserved, it was too easily interpreted as a form of arrogance."

Ouch, that hit's close to home!

"Our marriage was formed by the things Christopher knew and the things I did not."

"Our marriage was formed by the things Christopher knew and the things I did not."

But really, the nameless narrator seemed to know quite a bit more than we were led to believe.  She knows her husband is unfaithful.  She knows they are separated.  She knows her husband's family never liked her.  What she doesn't know, is where he might be.

Christopher's whereabouts is the central mystery of the novel, but I really don't consider this to be typical of the genre.  The writing style was almost stream of consciousness, very little dialog.  You learn about the marriage and consequent separation through the narrators memories and thoughts.  I was more drawn to how she lived her life, drifting along waiting for a push in any direction.  I don't want to give anything away, you really need to read this and experience it yourself!  It's a quick read, made quicker by not being able to put it down and walk away.
