The Silent Corner - Dean Koontz

The Silent Corner is the first novel in the Jane Hawk series.

Jane Hawk was an FBI agent. Now she's a fugitive from justice. Jane's husband was a Marine Corps officer. When Jane's husband committed suicide Jane couldn't believe it. She was right to not believe it. The plot she's uncovered is more sinister than you can imagine. Jane is on the run, but she's running toward the monsters who programmed her husband to kill himself. When she finds them they'll regret it. Very highly recommended.
