New and Selected Works

Truth, art, beauty, friendship -- what's worth the risk?

On assignment from the government, Marian Warner heads to a small town in Ohio to investigate the hostilities erupting when an old mission house is nominated for landmark status. Soon the battle goes from nasty letters to a double murder, and Marian discovers this small-town crime strips away the defenses it's taken her years to erect -- and those of someone she loves.

A Killer's Guide to Good Works new ebook cover.jpg



“Anything I want to read or write comes down to three words: Good Person Struggling. With institutions that don’t make sense. With relationships that strip the heart bare. With the wickedness we can never quite believe exists. Out of that story of struggle, hope starts small, sometimes stays small, but that’s all we really need.”
