This Christmas, first-year ballet student Isibéal O'Donnell is swept into a glittering holiday romance with Felix Catton, the golden boy who seems to have a direct line to joy, warmth, and Christmas magic itself. At the Cattons' enchanting Saltburn estate, their bond deepens under twinkling lights and a towering tree worthy of Santa's envy. But as Santa checks his list twice, the season turns... and Saltburn's holidays will end not just with love, but with murder, crime, and blood.
