Mark Z. Danielewski (/ˈdæniəlɛfski/; born March 5, 1966 is an American fiction author. Though his second novel, Only Revolutions (2006), was nominated for the National Book Award, Danielewski is most widely known for his debut novel House of Leaves (2000), which garnered a considerable cult following and won the New York Public Library's Young Lions Fiction Award. He has published one novella, The Fifty Year Sword, which until rereleased by Pantheon in the United States in 2012, remained relatively obscure due to only 2000 copies being published in the Netherlands (2005, De Bezige Bij).[7] Although several shorter works have been published, notably "All the Lights of Midnight: Salbatore Nufro Orejón, 'The Physics of Eror' and Livia Bassil's 'Psychology of Physics'," "Parable no9: 'The Hopeless Animal and the End of Nature,'" "Clip 4," and "Parable no8: 'Z is for Zoo,'" they've almost all been completely ignored by critics (though not fans). His latest project is The Familiar, an ambitious 27-volume serial novel whose first installment, The Familiar, Volume 1: One Rainy Day in May, was released on May 12, 2015. The Familiar, Volume 5: Redwood completed Season One when it was released on October 31, 2017.
