The oxblood effect

Retired and discredited intelligence agent Cass Gillett comes home to her birthplace, a small town in southern Colorado, only to find that old enemies lie in wait and she is once again in the crosshairs of a sniper's rifle. Her first impulse is to run away--she has no base of support, and no desire to persue the dangerous life again. But as the extent of a lethal plot becomes clearer, Cass knows that she can only come to grips with it--or die trying.
