Context paragraphs:
Bram Stoker: Abraham "Bram" Stoker (8 November 1847 – 20 April 1912) was an Irish author, best known today for his 1897 Gothic novel "Dracula".  During his lifetime, he was better known as the personal assistant of actor Henry Irving and business manager of the Lyceum Theatre in London, which Irving owned.

The Snake's Pass: The Snake's Pass is an 1890 novel by Bram Stoker.  It centers on the legend of Saint Patrick defeating the King of the Snakes in Ireland.  The novel also centers on the troubled romance between the main character and a local peasant girl.  "The Snake's Pass" was Bram Stoker's second imperial fiction novel, and was first published in the United Kingdom in 1890.  The novel is a precursor to Stoker's "Dracula" but was his only novel written in his native land of Ireland.

Dracula the Un-dead: Dracula the Un-dead is a sequel to Bram Stoker's classic novel "Dracula".  The book was written by Bram Stoker's great grand-nephew Dacre Stoker and Ian Holt.  Previously, Holt had been a direct-to-DVD horror screenwriter, and Stoker a track and field coach.

Bram Stoker's Dracula's Guest: Bram Stoker's Dracula's Guest (also known as just "Dracula's Guest") is a 2008 film that was written and directed by Michael Feifer.  It was released direct to video in August 2008 and is loosely based on Bram Stoker's 1914 novel "Dracula's Guest and Other Weird Stories".

Bram Stoker's Dracula's Curse: Bram Stoker's Dracula's Curse (also known simply as Dracula's Curse) is a 2006 horror film by The Asylum, written and directed by Leigh Scott.  Despite featuring Bram Stoker's name in the title, the film is not directly based on any of his writings or a mockbuster to the 1992 film "Bram Stoker's Dracula", but shares similarities to films such as "", "Dracula 2000", "" and "Van Helsing".  The film also shares some similarities with the 1971 Hammer horror film "Countess Dracula", which also features a Dracula-esque femme fatale in the lead role.

Gothic fiction: Gothic fiction, which is largely known by the subgenre of Gothic horror, is a genre or mode of literature and film that combines fiction and horror, death, and at times romance.  Its origin is attributed to English author Horace Walpole, with his 1764 novel "The Castle of Otranto", subtitled (in its second edition) "A Gothic Story".  The effect of Gothic fiction feeds on a pleasing sort of terror, an extension of Romantic literary pleasures that were relatively new at the time of Walpole's novel.  It originated in England in the second half of the 18th century where, following Walpole, it was further developed by Clara Reeve, Ann Radcliffe, William Thomas Beckford and Matthew Lewis.  The genre had much success in the 19th century, as witnessed by Mary Shelley's "Frankenstein" and the works of Edgar Allan Poe.  Another well known novel in this genre, dating from the late Victorian era, is Bram Stoker's "Dracula".  The name "Gothic" refers to the (pseudo)-medieval buildings, emulating Gothic architecture, in which many of these stories take place.  This extreme form of romanticism was very popular in England and Germany.  The English Gothic novel also led to new novel types such as the German "Schauerroman" and the French "Georgia".

Bran Castle: Bran Castle (Romanian: "Castelul Bran" ; German: "Törzburg" ; Hungarian: "Törcsvár" ), situated near Bran and in the immediate vicinity of Brașov, is a national monument and landmark in Romania.  The fortress is situated on the border between Transylvania and Wallachia, on DN73.  Commonly known as "Dracula's Crib" (although it is one among several locations linked to the Dracula legend, including Poenari Castle and Hunyad Castle), it is often erroneously referred to as the home of the title character in Bram Stoker's "Dracula".  There is, however, no evidence that Stoker knew anything about this castle, which has only tangential associations with Vlad the Impaler, voivode of Wallachia, the putative inspiration for Dracula.  As discovered by the Dutch author Hans Corneel de Roos, the location Bram Stoker actually had in mind for Castle Dracula while writing his novel was an empty mountain top, Mount Izvorul Călimanului, 2033 m high, located in the Călimani Alps near the former border with Moldavia.  Stoker's description of Dracula's crumbling fictional castle also bears no resemblance to Bran Castle.

The Book of Renfield: The Book of Renfield: A Gospel of Dracula is a 2005 novel written by Tim Lucas and the first of the "mash-up" horror-themed novels that rose to commercial prominence later in the decade.  It is an unofficial prequel to Bram Stoker's Dracula.  Like the original novel, "Renfield" is an epistolary novel written in series of written documents.  It focuses mainly on Renfield, mostly remembered for his minor role in "Dracula" as a lunatic that ate flies, rodents and other animals, and Dr. John Seward, the administrator of an insane asylum who is trying to understand Renfield's psychosis.
