As the town's self-appointed Marshall of Love and Justice, Carol Blake has played postmistress and matchmaker in Kiel, Wisconsin, for nearly fifty years. It is no accident that a lady's magazine, intended for one lonely divorcée, mysteriously appears in a grieving widower's box. Sparks fly when a mistress' lingerie catalog is bundled with the cheater's mail.
Being the postmistress has its perks. She parks wherever she wants, and no one stands in her way of completing her appointed rounds. Carol has dirt on everyone. Who knows your business more than the mailman?
Now, Carol is growing weary. The hundreds of victims shot by her arrows of love—or poison—either love her or hate her. Who will take Cupid's place in the small Wisconsin town of Kiel when she retires? Can the remainder of Kiel's citizens rest easy? Carol must choose from among the most unlikely of recruits. Is it too late for her to get shot by one of her own arrows?
