Description:In Dublin, Ireland, academics and historians are dying. An unidentified venom is to blame. Strange markings from deep in the Emerald Isle’s past suggest adherents to lost and forbidden knowledge may have reorganized. Detective Aileen O’Donnell of Ireland’s National Police Service, An Garda Síochána, has never heard of the agency’s sub rosa unit devoted to investigation of the strange and paranormal. That is, until a shooting incident leads to her suspension from the Special Detective Unit. While awaiting disciplinary proceedings, she’s pressed into service by the secret division to investigate the deaths and what might be the tip of a conspiracy and academic cover-up. Soon O’Donnell’s teamed with Geoffrey Bullfinch and Wendell "Mack" Macklemore of O.C.L.T. On a race through medieval ruins and holy sites, she must collect puzzle pieces, fragments from a forgotten pulp writer and bits of secret Druid history to stop the shadowy band of disciples before it awakens something long sleeping beneath one of Ireland’s most famous landmarks, something modern technology and firepower can’t defeat.
