Five Irish siblings aim at a fresh new beginning in Hogwarts School of Witchcraft and Wizardy after the tragic murder of their father. New friends are made - including The Marauders -, old friends are already there, and (as always in Hogwarts), unusual things stir into a delightfully dangerous potion. When the five arrive they decide to show Hogwarts how the Irish like to have craic(fun). Be careful because The Irish Are in Hogwarts Havin' The Craic!
