My cousin, Marjorie Harshaw Robie, has just published "Dwelling Place of Dragons: An Irish Story".
Despite the title, I understand it's based on the diaries of James Harshaw, a Presbyterian in Ulster during the middle of the 19th century. For more, see here.
I'm getting it for Christmas and will report on it when I've read it. But family loyalty says it's unfortunate the timing is too late for the NYTimes books of the year list.
