John Ajvide Lindqvist is a Swedish author, born in 1968. He grew up in Blackeberg, a suburb of Stockholm. He wanted to become something awful and fantastic. First he became a conjurer and came in second in the Nordic card trick championship. Then he was a stand-up comedian for twelve years, before writing Let the Right One In. That novel became a phenomenal international bestseller and was made into a film and a West End play, both called Let Me In. His books are published in twenty-nine countries worldwide.
