With The Mysteries of Udolpho, Ann Radcliffe raised the Gothic romance to a new level and inspired a long line of imitators. Portraying her heroine's inner life, creating a thick atmosphere of fear, and providing a gripping plot that continues to thrill readers today, The Mysteries of Udolpho is the story of orphan Emily St. Aubert, who finds herself separated from the man she loves and confined within the medieval castle of her aunt's new husband, Montoni. Inside the castle, she must cope with an unwanted suitor, Montoni's threats, and the wild imaginings and terrors that threaten to overwhelm her.

This new edition includes an introduction that discusses the publication and early reception of the novel, the genre of Gothic romance, and Radcliffe's use of history, exotic settings, the supernatural, and poetry.
