Good men are dying—and the case just turned personal.

Men are dying across the Pacific Northwest, their bodies found near churches and charities, each with valentine candy hearts shoved down their throats. Then the case takes a shocking turn when the father Laurel has never met—a former pastor—is attacked the same way.

Now Laurel must solve the case and find where her father has been, all while her brilliant sociopath half-sister Abigail insists they've both inherited their father's malignant narcissism. Assisting her is Fish and Wildlife captain Huck Rivers, whose gut instinct puts him at odds with her analytic approach—until the killer hones in on Huck's own dark secrets.
