Dracula by Bram Stoker (1897). Another reread here -- though my previous reading was pre-teen via a Scholastic Books edition, which I'm sure was abridged. So probably my first run through the full text. You know the story... bat meets girl, bat bites girl, girl becomes immortal blood-sucking demon. None of the movies have ever stuck completely to the text -- nice to take in the unaltered original plot. One significant thing the book brings out, that I have not seen in any of the movies, is the scale of Dracula's ambitions when moving to England. It usually just comes off as a touristy jaunt for fresh blood, while in the book, Dracula ships over a whole load of boxes containing his native earth and begins distributing them to safehouses scattered about the nation -- ultimately planning to take over the world with his new, viral race of vampires. Stoker does a fairly gripping job with prose that is not all that dated (though there are some Victorian quirks, such as referring to children as "it" rather than "he" or "she"; or blind faith in the superior nature of proper English gentlemen). Leisurely when building atmosphere, gradually accelerating to a fever pitch for the final conflict. The great narrative device is that the whole story is told through various characters' journal entries and letters, along with a few newspaper clippings (inspiring the current Dracula Blogged project). Stoker is by no means the first to do this, but it works excellently with the material, leaving the reader to connect the dots that the characters are disastrously unaware of. It must have been even more effective when it was an unknown story. The movies have helped keep the story alive through this century-plus, but Stoker defnitely built a solid base for them to exploit. And no, the line, "I vant to drink your bloo-ood," never appears. Dig around online and you'll find more analysis, history and fandom than you'll ever need.
