When a winter storm blows in from Lake Erie to freeze western New York State, vineyard workers scramble to protect their crops. But they aren’t the only ones facing brutal wind and snow. Someone is using the storm as cover for a grisly crime – and the timing puts an end to State Police Investigator Mac Llewellyn’s leave. Mac knows that homicide has no societal boundaries but as he navigates the trendy world of grape-growing, fine wines, and winery tours, he discovers the high-stakes competition might lead someone to crush more than grapes.

Meanwhile, Shay Flaherty’s business has taken an unexpected spin and her once-roomy house is suddenly too small. Everywhere she turns, someone needs her attention and her unfinished tasks are piling up. So when Mac suggests a very special evening out, she eagerly accepts. A break in routine is just what she needs… or is it?
