Macie Connor can't resist throwing a penny in Bethesda Fountain every time she goes on a date—even though the date never works out. Who knows? Maybe luck will smile on her this time. Or maybe she's just unlucky, like her dead sister Karen. Karen's handsome ex-boyfriend Rylan wants Macie to help him find her sister's killer. All she wants is to put it behind her—and end her attraction to a man she can't have. But the closer they get to the murderer, the closer danger draws them together.
