Three are based on best selling books, LJ Smith's Vampire Diaries and Stephenie Meyer's Twilight aimed at teenagers, Charlaine Harris' tongue-in-bloody-cheek True Blood a more adult market.
Even the relatively tame British blood fest Being Human has spin-off novels.
Now the fangs phenomenon casts its shadow upon the Fylde. Be afraid but not too afraid, for this time Dracula demonstrates a fine pair of lungs, too.
Ambitious theatre company, AV Productions, presents Broadway musical Dracula at Lytham's Lowther Pavilion on Friday and Saturday.
Back in the book world, one best selling author is aiming right for the jugular of the lucrative young market.
Justin Somper is gaining ground on Meyers and co, his market of 10-plus year olds, sated on Mona the Vampire as kiddies, now being joined by older readers. Fans are not only staying loyal to the series, which started five years ago, but others are coming to it, too.
Vampires are the biggest comeback kings since Pirates of the Caribbean breathed new life into the realm once reserved for Robert Louis Stevenson.
There was gold in the buried treasure of box office pirates – but a far richer seam could be mined in the veins of sexy blood suckers.
But just who would win in a fight? Vampires or Pirates?
Somper, known as The Captain to his young fans, set the scene for the ultimate crossover conflict: Vampirates. Yo ho ho and a bottle of blood?
He takes readers to the deep blue yonder of blood red sunsets sinking on sodden boards of vanquished pirate ships.
As Adam Lancaster, chair of the Federation of Children's Book Groups, points out: "Before Edward and Bella (Twilight), there was Lorcan and Grace (Vampirates)."
Tomorrow's World Book Day marks the
release of Empire of the Night, the fifth novel in the highly charged Vampirates saga, for readers aged 10 plus 44 years in in my case.
As with the Harry Potter books, there's a lot of closet adult
readers, tipped to turn up when Justin shows up in the flesh at
Silverdell's bookshop in Kirkham on March 24.
Justin, who still works as a book publicist, knows his market better than most, so blogs, and twitter feeds to fans, nicknamed the
Nocturnals, in homage to his creations.
They have also launched an online petition for the books to be turned into films. In last year's Ultimate Book Guide Vampirates came number two in the -readers' poll of "Books That Should Be Filmed".
Justin's well read, himself, and influences such Fitzgerald, Joyce, Hemingway, Salinger resonate in some of his characters.
One of his most popular vampires, Lorcan Furey, has a flavour of Michael Furey (from James Joyce's Dubliners' The Dead) about him.
Somper's romping through it all and having a ball. Apart from looking forward to a themed icecream with lashings of raspberry ripple and perhaps a choc flake doubling as a stake, at Silverdell, he's dropping by at Baines High School that morning.
And he's now completing his sixth novel.
The cover of his fifth, Empire of the Night, features on 75,000 postcards, part of a cinema campaign alongside the release of Percy Jackson and the Lightning Thief movie, based on Rick Riordan's books for a similar age range as Somper's market.
They offer a free download of book one in the series, Demons of the Ocean. The first proved such a success with its heady mix of bloodthirsty vampires and swashbuckling pirates, publishers Simon & Schuster brought forward publication of the second, Tide of Terror, besieged with fans desperate for more on their heroes, orphan twins Connor and Grace Tempest.
Of course, the genesis of the latest incarnation can be traced back to Stoker's gothic masterpiece in 1897, and given a choice of vampires, by whose fangs he would prefer to meet his maker, Justin plumps for the original. "The book, not the film, version. Not that I'd want to be a vampire. It's a ticket to fun and immortal partying but I'd still prefer to walk my dog on a sunny day."
Of the TV series, he enjoys True Blood, the second series of which has been pounced upon by Sky. "The writing's sharp, develops the outsiders' angle, and I love the stylish wit of the opening credits."
As for Vampirates? "I still aim to grab people by the throat. I took the first to eight publishers, four of who said no, we don't get it, but followed by two or three who took it seriously, and one who not only bought the first, but wanted at least four more.
"I was advised it was a treadmill but I enjoy it, it's a great experience, and I love the interaction with readers, whether online, or schools, or those marvellous independent bookshops, such as Silverdell, good as the chains have been to me.
"The core group is 10 to 15 but younger kids are coming up now than when it started - and older ones too.
"And there's a new generation of Vampirates just waiting to meet them..."
