Darragh Hoghter is unusual among Irish-Americans. First there is his nearly unpronounceable name. Then there is his black cat named Merlin. But mostly he is set apart because he comes from a long line of Irish Druids. To his family has fallen the responsibility of ridding the world of a serial killer and to do so will require all the supernatural abilities his family can create. Adding to his arsenal of weaponry is Keith Hunt, a lieutenant in the Fort Lauderdale Police Department who helps with the investigation. The Passion of the Druid is set largely in Fort Lauderdale with the story beginning in England and continuing briefly in Tulsa, Oklahoma. The places named are largely actual points of interest in these locations and most are places that the author has visited.
