Her passion for myth and magic leads a woman into the heart of a murderous evil On a remote stretch of the rugged coast of Ireland, folklorist and illustrator Keira Sullivan pursues the mysterious Irish legend of an ancient Celtic stone angel. As she searches an isolated ruin, she's certain she's discovered the mythic angel, but before she can examine her find, she senses a malevolent presence...Is someone in there with her? Then the ruin collapses, trapping her. Keira's uncle, a Boston homicide detective, enlists the help of Simon Cahill to find his missing niece. Simon, an expert with Fast Rescue, a rapid response search-and-rescue organization, is trying to keep a low profile after secretly assisting the take-down of a major criminal network, but he rushes to Ireland, pulling Keira out of the rubble just as she's about to free herself.
