But Not Forgiven — B.J. Bourg

When a woman is found dead on her doorsteps -- shot through the heart with an arrow -- Clint Wolf and Susan Wilson go to work trying to track down the sadistic killer. On the very next day, a second victim is murdered in his driveway (killed in the same manner) and it's now a race against time to uncover the motive behind the killings and identify the murderer. What they know so far is that he's a skilled archer preying on human targets, and they have no clue where he'll strike next. As though the case itself isn't complicated enough, the district attorney has launched a grand jury investigation into Susan's actions during a shooting that saved Clint's life. No one knows exactly why the DA is gunning for Susan, but one thing is crystal clear...it's personal.
