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 C chulainn 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.
