The Castle of Wolfenbach by Eliza Parsons
Matilda Weimar flees her lecherous and incestuous uncle and seeks refuge in the ancient Castle of Wolfenbach. Among the castle's abandoned chambers, Matilda will discover the horrifying mystery of the missing Countess of Wolfenbach. But when her uncle tracks her down, can she escape his despicable intentions? One of the seven "horrid novels" named in Jane Austen's Northanger Abbey, The Castle of Wolfenbach is perhaps the most important of the early Gothic novels, predating both The Mysteries of Udolpho and The Monk.
