After three numbing years, she has forsaken her husband and escaped to mythical Ireland where a stalker leaves her calling cards that are eerie and increasingly gruesome. Shadowed by the legend of the warrior hero Cuchulainn and preyed upon by her own escalating imagination, Leah finds her escape is turning into a virtual prison of chilling mind-games and cold-hearted crimes.
