A quiet summer in Ireland? Not a hope! One of the country’s most precious treasures has been stolen from the National Museum and a chalice has gone missing from an archaeological dig at Lough Derg. Those two robberies are mysteriously connected to a house in Dublin, and only Mac Dara and Ána, two teenagers on a visit from New York, have made the connection. Can Mac Dara and Ána escape the clutches of an international smuggling ring? Can they retrieve the stolen treasures? And will they ever see their parents again?
