PositiveThe New York Times Book ReviewIn The Last Castle, Denise Kiernan tries to reveal the answer to what is surely the greatest mystery for any of Biltmore’s million annual visitors: Who, exactly, conceived of such a huge undertaking? What kind of bachelor really wanted to inhabit a 250-room house, replete with an indoor swimming pool and bowling alley? Kiernan hangs her dense narrative on a potential love story featuring an unlikely lead … Kiernan’s wider lens on the Gilded Age compensates for her protagonists’ insipidness. The book’s vitality lies in the details she reveals about the architects, writers, artists and peers of the Vanderbilts who spent time at Biltmore.
